Iodine-131 Therapy

What are the prerequisites for having Iodine-131 therapy done? Endocrine specialists generally refer patients for these treatments. All women who are not yet menopausal must have a blood test on the day of the treatment to ascertain pregnancy status. This is at the nuclear medicine physician’s discretion. For patients having an ablative dose as a... View Article

MIBG scan

What are the prerequisites for having an MIBG scan done? A MIBG scan is commonly used for detection of neuroendocrine tumours such as neuroblastoma and phaeochromocytoma. It can also aid detection of carcinoid and medullary thyroid carcinoma. Results of serum and urinary catecholamines may be necessary prior to approval of the scan by the nuclear... View Article

Nuclear Medicine

What are the precautions for children and pregnant patients who require a nuclear medicine procedure? Nuclear medicine studies are frequently used in children, and the dose of the administered radiopharmaceutical is adjusted to the patient’s weight. As for all imaging studies involving ionising radiation, it is important that careful consideration is given to carrying out... View Article

Nuclear Medicine Bone Scan

What are the generally accepted indications for a bone scan? Nuclear medicine bone scans are used to evaluate and localise bony pathologies. They are useful to assess the source of presumed bone pain, such as hip pain or foot pain. Bone scans are often used as a complementary study to further investigate abnormalities found on...

Nuclear Medicine Cardiac Stress Test

What is a Nuclear Medicine (NM) Cardiac Stress test? A Nuclear Medicine (NM) cardiac stress test involves a scintigraphic (radioactive isotope) scan of the heart in conjunction with an exercise stress test to evaluate myocardial perfusion. The stress test usually uses treadmill exercise, but when the patient is unable to exercise then “stress” can be pharmacologically... View Article

Nuclear Medicine DMSA Scan

What are the prerequisites for having a DMSA scan done? No prerequisites. A recent or current UTI may demonstrate a lack of radiopharmaceutical accumulation due to pyelonephritis. This may resolve on further imaging or reflect permanent scarring. It is usual to wait 8-12 weeks following a recent infection before performing a DMSA scan, unless you... View Article

Nuclear Medicine Gated Blood Pool Scan

What are the prerequisites for having an gated blood pool scan done? There are no pre-requisites for this study. What are the absolute contraindications for an gated blood pool scan? This study may not be suitable for pregnant women. The benefit versus risk should be discussed with the nuclear medicine specialist. Women who are breastfeeding... View Article

Nuclear Medicine Renal Scan

What are the prerequisites for having a renal scan done? Patients for a captopril renogram, when investigating for RAS or renovascular hypertension will need to have their ACE inhibitors discontinued for 4-7 days prior to study; Renal ultrasound may be required prior to nuclear medicine renal scan if there is suspicion of: duplex or dilated...

Nuclear Medicine Thyroid Scan

What are the prerequisites for having a thyroid scan done? Thyroid serum measurements of TSH, T4, T3, thyroglobulin, TSI, TPOAb as required; Ultrasound study of thyroid gland if nodules are suspected; Patient should not have any radiological procedure that requires the infusion of iodine contrast medium at least 8 weeks prior to scanning (CT most... View Article

Octreotide Scan

What are the prerequisites for having an octreotide scan done? No fasting is required prior to procedure; A relevant history of the type of suspected or known primary tumour, its hormonal activity, the results of other imaging studies (CT, MRI), laboratory results (tumour markers), history of recent surgery, chemotherapy, radiation therapy and octreotide therapy should... View Article

Parathyroid MIBI Scan

What are the prerequisites for having a parathyroid MIBI scan done? Documentation of an elevated serum calcium and parathyroid hormone. Documented increased urinary excretion of calcium is also advised when other laboratory abnormalities are mild. History of prior thyroid or parathyroid surgery should be provided; Results of CT, MRI or ultrasound scans including any other... View Article

PET Scan

What is a PET scan? PET stands for “positron emission tomography”. It is a nuclear medicine imaging test in which an injected radiolabeled molecule enables functional imaging, typically of a metabolic pathway or cell surface receptor. To date, this has mainly been applied for cancer imaging, but it is also useful for imaging inflammation, infection... View Article


What are the prerequisites for having a SPECT-CT scan done? Referral for a SPECT-CT scan is usually done after consultation between the nuclear medicine specialist and the referrer. The nuclear medicine specialist may consider the SPECT-CT to be helpful in delineating pathology when standard planar gamma camera imaging is difficult to interpret. What are the... View Article

VQ Scan

What are the generally accepted indications for VQ Scan? A ventilation–perfusion (VQ) scan evaluates the airflow (ventilation) and blood flow (perfusion) in the lungs. They are used in several clinical settings for: the diagnosis of a suspected pulmonary embolus; and the assessment of regional lung function. Other indications are quantifying right to left shunts and... View Article

Whole Body MIBI Myeloma Scan

What are the prerequisites for having a whole body MIBI myeloma scan done? As the scan involves an injection of radioactivity, it is not advisable in pregnant females.
