Parathyroid carcinoma is very rare, with only a few documented cases. Hence, metastatic lesions are infrequently documented on scintigraphic imaging. We present a case of a 63-year-old female presenting with elevated serum levels of ionized calcium and parathyroid hormone (PTH) who was referred to our department for a parathyroid scan with SPECT/ CT. Parathyroid scintigraphy showed a focus of i...

Incidental extra-osseous uptake of 99mTc-MDP on bone scintigraphy has been frequently reported in the literature; however, calcification of the psoas muscle is a rare condition, which has been reported on magnetic resonance (MR) and computed tomography (CT) imagings. Here we report a 67-year-old woman with acute paraplegia and low back pain who was referred for a 99mTc-MDP...

Owing to their minimally invasive nature, efficiency and availability, radionuclide renal diagnostic studies play an important role in assessing renal transplant function. Various quantitative parameters have been derived from the radionuclide renograms in the follow-up to assess changes in perfusion and function of the transplant kidneys. The aim of this study was to evaluate the changes in re...

a 29- year old female with bone pain and history of precocious puberty was referred for bone scintigraphy. on physical examination café au lait macular spots were noted on her neck, buttocks and left leg. bone scan showed multiple areas of intense increased activity which was in favour of polyostotic fibrous dysplasia. considering the presence of polyostotic fibrous dysplasia, precocious pubert...

Current treatment of metastatic bone prostate cancer with Docetaxel chemotherapy per CHAARTED trial is standard of care. Timing of CT and bone scintigraphy for evaluation of successful treatment of lytic lesions is not available in the literature. We present a case of a 70 year old male with PSA of 586 and wide spread metastatic bone lytic lesions, who underwent androgen deprivation therapy and...

Soft tissue uptake of Tc-99m labeled bone seeking agents, such as Tc-99m 3,3-diphosphono-1,2-propanedicarboxylic acid (DPD), is commonly seen in clinical practice, even though bone scintigraphy is mainly used to detect bone disease. However, gastric uptake of bone agents in patients with gastric cancer is very rare. And it has been reported that calcified gastric adenocarcinoma appears in only ...

Measurement of colon transit time is the most basic and primary tool in evaluating disorders of colonic motility. In particular, it is helpful in pathologic diagnosis and for planning management in patients with constipation. Several techniques for measuring colon transit time currently exist. The standard measurement of colon transit time has been performed using radioopaque marker test. The r...

The hypercalcemia of hyperparathyroidism (HPT) can cause devastating effects to the patient and only surgical removal of the hyperfunctioning parathyroid tissue can definitely cure the disease. Radionuclide parathyroid imaging has no role in the diagnosis of hyperparathyroidism or in the selection of the type of treatment. However, once surgery is decided (99m)Tc-sestamibi scanning can localize...

Lymphoedema is a life-long disease which may be improved but not healed by our therapy. Therefore it seems to be desirable to ascertain the clinical suspicion of lymphoedema or to rule out this diagnosis at least once in the life of a patient suffering from chronic swelling of the extremities. The most appropriate methods for that purpose are lymphoscintigraphy and indirect lymphography. Radion...

Cardiac nuclear medicine refers to three techniques: 1. Radionuclide ventriculography (RNV, also known as MUGA) 2. Myocardial perfusion scintigraphy (MPS) 3. Positron emission tomography (PET) Radionuclide ventriculography has been largely superseded by echocardiography. Occasionally it is helpful in determining ventricular function when echocardiographic views are limited and there is a contra...
