Inguinoscrotal hernias that contain bladder diverticulae are a rare occurrence. We report the case of a 85 yearold man with intense radioactivity overlying the left pubic tubercle on [Tc99m]-methylene-diphosponate (MDP) bone scan. SPECT/CT imaging established the diagnosis of excreted urinary radioactivity within a large herniated bladder diverticulum. SPECT/CT is a useful technique for evaluat...

BACKGROUND Cardiovascular disease is common cause of death in developed as well as developing countries. The most common cause of Ischemic Heart disease is narrowing of coronary arteries, a process called as atherosclerosis. The objective of the present study is to determine the pattern of ischemic changes detected by technetium tetrofosmin (Tc99m). METHODS Sixty five patients presenting as k...

Bone scintigraphy has some limitations in detecting bone lesions at the time of diagnosis since Tc99m MDP scintigraphy does not trace lesions lacking osteoblastic activity3. Tc99m Sestamibi (MIBI) has been proposed as a potential tracer in patients with multiple myeloma, as its increased uptake in the bone marrow has been reported as an indicator of myeloma activity4. It has been suggested to b...

It has been established that a cationic gold(I)/(R)-DTBM-Segphos or (R)-BINAP complex catalyzes the atropselective intramolecular hydroarylation of alkynes leading to enantioenriched axially chiral 4-aryl-2-quinolinones and 4-arylcoumarins with up to 61% ee.

Dl-lsoleucine was complexed with Thioglycolic acid in the presence of Stannous ions to label with TC99m-Pertechnetate. Percentage labeling was determined by paper chromatography. Preparations of more than 95% labeled with Tc99m were injected to rabbits for imaging and tissue distribution studies. Tc99m.TGA.l LEU complex was investigated as a myocardial imaging agent with respect to its kinetics...

Four patients with sonographic suggestion of hepatic hemangioma are studied with Tc99m-labeled RBC scan. The scan findings are compaired with other imaging modalities. Lesions as small as 36 mm could be detected by this method. Tc99m labeled RBC scan is a valuable tool to differentiate hepatic hemangioma from other space occupying lesion of the liver.

Technetium labelled Sucralphate has been used as an ulcer scanning agent in the gastrointestinal tract. The labelling described in the literature involves incubation of Tc99m-HSA (Human serum albumin) with Sucralphate. Due to difficulty in obtaining HSA we used bovine serum albumin (BSA) to tag radioactivity with Sucralphate. The radioactive yields (Tagged Sucraiphate and Tc99m-BSA) obtained af...

We describe a case of a 58-year-old male with longstanding hypertension and Type 2 diabetes mellitus who developed sudden onset renal impairment. The first clue to the possible presence of amyloidosis in this case was provided by the radionuclide renal cortical scan performed with trivalent dimercapto succinic acid (Tc99m-DMSA-3), which revealed intense tracer uptake in the spleen suggesting am...

PURPOSE To explore the role of single-photon emission CT (SPECT) in initial diagnostic evaluation of patients with mild traumatic brain injury (MTBI) and to identify subgroups in which it may serve as a useful diagnostic tool. MATERIALS AND METHODS Patients with MTBI seen during a 14-month period were prospectively included in this study. All patients had a CT of head within 12 hours of injur...
