EXAMINATION & SAFETY EXAMINATION & SAFETY Give us a call if you are unsure about the preparation and safety of your test at 28682888. COMPUTED TOMOGRAPHY (CT SCAN) INTRODUCTION CT Scan is a painless and non-invasive medical imaging technique. CT scan combines x-rays and computer technology to obtain detailed and precise images of the body in virtual slices and in the three dimensions of space inside the body. CT Scan is one of the ideal methods for both preventive and diagnostic examinations. It is very useful in the early detection of coronary heart disease, lung cancer, colon cancer and bone diseases. CT Scan is useful in evaluating body organs, such as the brain, spine, neck, heart, breast, liver, gallbladder, pancreas, kidney, urinary bladder, prostate gland, uterus and ovaries, bone, joints and soft tissues. During the examination, an injection of a contrast medium is sometimes necessary to enhance tissue and disease visualization. PREPARATION Do not eat or drink for 4 hours before the exam. EXAMINATION DURATION Usually15-30 min. ​ MAGNETIC RESONANCE IMAGING (3.0T MRI) INTRODUCTION Magnetic resonance imaging (MRI) is a painless and non-invasive medical imaging technique allowing doctors to obtain detailed and precise images of the body in virtual slices and in the three dimensions of space inside the body. MRI uses a powerful magnetic field and radiofrequency waves to generate digital images. MRI has no radiation and it does not use x-rays. MRI is the ideal method for both preventive and diagnostic examinations. MRI is very useful in the cancer screening, solid organ cancer detection and local staging, heart ischaemia and function assessment; brain, spine and nerve diseases diagnosis; bone and joint diseases diagnosis, as well as sports injury. MRI is useful in evaluating body organs, such as the brain, spine, neck, heart, breast, liver, gallbladder, pancreas, kidney, urinary bladder, prostate gland, uterus and ovaries, bone, joints and soft tissues. During the examination, an injection of a contrast medium might be necessary to enhance tissue and disease visualization. PREPARATION ​ The presence of metal in your body may be a safety hazard or affect a portion of the MRI image. If you have any metal or electronic devices in your body, such as metallic joint prostheses, artificial heart valves or cardiac stents, an implanted heart defibrillator, a pacemaker, metal clips, cochlear implants, a bullet, shrapnel or any other type of metal fragment, please inform our staff immediately. Before you schedule an MRI, tell your doctor if you think you’re pregnant. Your doctor may recommend choosing an alternative exam or postponing the MRI. Before an MRI exam, eat normally and continue to take your usual medications, unless otherwise instructed. You will be asked to change into a gown and to remove jewelry, hairpins, eyeglasses, watches, wigs, dentures, hearing aids, underwire bras and metallic make-up. ​ EXAMINATION DURATION Usually 30-40 mins. ​ POSITRON EMISSION TOMOGRAPHY- COMPUTED TOMOGRAPHY (PET-CT SCAN) INTRODUCTION PET/CT scan makes use of images from two technologies in determining the exact location of an abnormality in the body and consequently, detecting diseases such as cancer and other abnormalities. ​ PREPARATION PET/CAT scanning is a non-invasive procedure that can take up to two hours. It is typically undertaken on an outpatient basis. The test begins by obtaining blood sugar level to ensure it is within PET scan parameters. The liquid radioactive material is injected. You will be asked to rest quietly on a chair for approximately one hour. You will then be moved to the scanning room and positioned on the scanning bed. The CT scan is done first and takes less than 2 minutes. The PET scan takes approximately 25 minutes, but the time will vary depending on the areas of your body being scanned. You should drink plenty of fluids after the test is finished to flush the radioactive substance out of the body. Diabetic Patients: Insulin Controlled Diabetes: Have a meal with your insulin 4 hours prior to your appointment Non-Insulin Controlled Diabetes: If you have a morning PET/CT appointment, please do not take your diabetic tablets on the morning of your scan but bring them with you so that you can take them immediately after your scan has been completed. If you have an afternoon PET/CT appointment, please take your diabetic tablets on the morning of your scan, not less than 6 hours before the time of your appointment. PET/CT Diet Plan: 24 Hours before your exam – No caffeine No exercise or participate in strenuous physical activity 6 Hours before your exam – Do NOT eat(including tube feeding) Do NOT chew gum or cough drops, etc Drink ONLY water without additives No smoking Take all prescribed medications.

MR Angiography MR Angiography What is magnetic resonance a a ngiography (MRA)? An MRI uses radio waves, a magnetic field, and a computer create a scan of your body to look for health problems. ​ Magnetic resonance angiography (MRA) is a type of MRI. It looks just at the body’s blood vessels. A regular angiogram requires inserting a thin tube (catheter) into your body. MRA is a not invasive and less painful test. ​ During MRA, you lie flat inside an MRI scanner. This is a large, tunnel-like tube. In some cases, contrast dye may be added to your bloodstream. This is done to make your blood vessels easier to see. The contrast is put into your vein with an IV (intravenous) needle. Why might I need MRA? If a narrowing or blockage of blood vessels somewhere in your body is suspected, your doctor may advise MRA. ​ Conditions that can be looked for include: An aneurysm or weakness in the wall of an artery A narrowing of the aorta (aortic coarctation) Bleeding in and along the wall of the aorta (aortic dissection) To find the cause of a stroke Narrowing or blockage of the vessels in the arms or legs Renal (kidney) artery stenosis, a narrowing of the blood vessels in the kidneys that can lead to high blood pressure and even kidney failure What are the risks of MRA? If a dye is needed to make the blood vessels easier to see during the test, you will have an IV inserted. ​ Some risks of MRA include: ​ You may have problems if you have metal implants (such as a pacemaker or bullet fragment) in your body. We will make sure if it is safe to have the scan beforehand. If you have a problem with your kidneys, you are at risk of a severe reaction from the MRA contrast dye. If you have a history of kidney disease, your healthcare provider may decide that an MRA is safe for you. Feeling anxious during the scanning procedure. Sedation might be needed for severe claustrophobia. The MRI scanner typically makes a lot of noise, including loud humming noises. The full scan may take an hour or longer depending on the type and number of blood vessels we have to scanned. ​ ​ Pregnant women may have additional risks in the MRI scanner. Make sure to tell your healthcare provider if you are or might be pregnant. ​ Book Now Continue

CT CT What is a CT scan? Multiple X-rays are taken rapidly from different angles around the body and then arranged by a high-speed computer to produce a cross-sectional view of the body. It can be used to see internal organs such as brain, neck, spine or extremities. For some CT scans, the radiologist injects intravenous contrast or dye to highlight certain tissues for closer examination. Some patients may also be required to drink oral contrast as well. A CT scan helps to accurately diagnose many diseases even in the early stages. ​ What happens during a CT scan procedure? You will be positioned onto the table for the scan. You will feel the table move and may hear a whirring noise or high-pitched beep. To get the most precise results, the technologist may ask you to hold your breath for a short time. Lie as still as possible to avoid blurring the images. You will be able to communicate with the technologist at all times during your scan. The scanning is done in less than 10 to 15mins. If contrast was used, drink plenty of water in the next 24 hours to help flush the contrast medium from your body. The radiologist will then review your scans and send the results to your physician. ​ What are the benefits and risks of a CT scan? CT scans are among the safest exams. Your body will be exposed to a very small amount of radiation. If you are pregnant, you should not have a CT scan without first discussing the risks with your doctor. There is a small risk you will have an allergic reaction to contrast dye. Common minor allergic reactions may include hives and itching. More serious contrast reactions are very rare. Be sure to tell us if you are allergic to any medications or chemicals such as iodine. Our staff are trained to handle any allergic reaction you might have. Book Now Continue

Coeliac Plexus Block Coeliac Plexus Block Coeliac plexus block under image guidance is a safe percutaneous procedure with good outcomes for pain palliation in patients who have chronic abdominal pain with advanced cancers, especially from upper abdominal viscera, such as the pancreas , stomach , duodenum , proximal small bowel , liver and the biliary tract, or due to enlarged lymph nodes. ​ Contraindications ​ severe uncorrectable bleeding disorder or low platelet count. inability to visualise local anatomy due to large overlying soft tissue mass or abdominal aortic aneurysm. ​ Technique Coeliac ganglia are located anterior to the dome of the diaphragm, over the anterolateral wall of the aorta bilaterally. Both anterior and posterior approaches may be used to access these, depending on the safest route of access. Alcohol of 50–100% is the commonly used neurolytic agent following the injection of local anaesthetics. ​ Postprocedural care Patients are usually admitted for close monitoring overnight. They should be kept well-hydrated. ​ Complications may include pain, low blood pressure, diarrhoea, bleeding, neurological complications or alcohol toxicity. ​ Book Now Continue

Thyroid Scanning Thyroid Scanning What Is Thyroid Disease? The thyroid gland produces hormones that control your metabolism, which affects every organ in your body. Having abnormally high or low levels of thyroid hormone can affect you in many ways. You may experience weight gain or nervousness from thyroid diseases. ​ Thyroid Ultrasound ​ Ultrasound examination is the most accurate and useful imaging test to detect nodules or lumps within the thyroid gland. It does not have radiation. Ultrasound procedure uses sound waves to produce images of the thyroid gland and the images can be captured to assess the size, shape, structure and any abnormalities of the thyroid gland. ​ Accurate measurement of the size of the thyroid nodules can be made using ultrasound imaging. It also assists in the evaluation of the variations in the thyroid tissue such as enlargement caused by goiter and decrease in size caused by inflammation and can differentiate between the solid, fluid-filled or complex type of thyroid nodules. Why Would I Need A Thyroid Ultrasound ? It may be used to: Detect goiter which is an enlargement of the thyroid gland Assess whether a lump originates from the thyroid gland or elsewhere Determine whether a mass is growing Differentiate between cysts, filled with fluid, and solid masses Help determine whether an abnormal growth may be malignant Thyroid Ultrasound Procedure During a thyroid ultrasound, the patient lies down with the neck hyperextended. The ultrasound transducer is placed over the area. You may feel some pressure from the transducer but the procedure is painless. The transducer generates sound waves that create images of the gland which are projected onto a computer screen. When sound waves make contact with fluid-filled cysts they create different patterns than when they make contact with solid tumors, so the ultrasound procedure is a valuable diagnostic tool. ​ Book Now Continue

Stellate ganglion block Stellate ganglion block Stellate Ganglion Blocks The stellate ganglion is a collection of sympathetic nerves found in the neck. The nerves are located in front of the cervical 6th and 7th vertebral body. They supply the face and arm. ​ Blocking the sympathetic activity by anesthetizing the stellate ganglion may relieve pain. ​ A stellate ganglion block is done to: Diagnose the cause of pain in the face and head, arms and chest Manage pain in the head, neck, chest or arm caused by nerve injuries, the effects of an attack of shingles (herpes zoster). Reduce sweating in the face, head, arms and hands Treat sympathetic maintained pain or complex regional pain syndrome A stellate ganglion block can be both diagnostic—ie done to find the cause of a patient's pain— and therapeutic—ie done to relieve the pain. How is a Stellate Ganglion Block done? The patient is usually sedated, and using ultrasound, a fine needle is placed near the stellate ganglion and anesthetic is injected. The patient will not feel numbness in the face. but will have a droopy eye, redness of the eye, warmth in the face and arm and may have hoarseness of the voice. These effects are temporary and last a few hours. Pain relief may be gradual and is tracked by a pain diary. ​ Book Now Continue
