Visualization of the kidneys during hepatobiliary scintigraphy using technetium-99m(Tc) labeled N -substituted iminodiacetic acid agents is often the consequence of severe hepatic dysfunction or biliary tract obstruction {}-3). We report a case of delayed renal visualization seen during hepatobiliary imaging with [Tc]diisopropyl-iminodiacetic acid (DISIDA) where no evidence for severe hepatic d...

We have compared [Tc-99m] sodium pertechnetate with Tc-99m glucoheptonate in 52 patients studied for various brain lesions. Flow studies as well as delayed scans were performed in all. Especially in primary and metastatic lesions of the posterior fossa, the diagnostic yield was improved by the delayed glucoheptonate (GH) scans. In contrast, no advantage of GH over pertechnetate could be detecte...

The extraction of pertechnetate ions from aquous solutions containing various concentrations of nitric acid into hydrophobic ionic liquids (ILs) has been examined at 25, 50 and 70 °C. The results show that the distribution ratio of Tc (DTc) between both phases weakly depends on the temperature and HNO3 concentration when IL's with relatively short aliphatic chains are used. The DTc obtained for...

OBJECTIVE Thyroid hemiagenesis is a rare congenital disorder characterized by the absence of a lobe and/or of isthmus. Studies on the association between thyroid hemiagenesis, Graves' disease and differentiated thyroid cancer are rare. CASE PRESENTATION We describe the medical and surgical history of a patient in whom a molecular evaluation was performed. A 36-year-old man presented with symp...

The clinical consequences of lower gastrointestinal bleeding range from trivial to life-threatening. Nuclear medicine imaging techniques allow identification of those patients who are actively bleeding. The demonstration of active bleeding not only provides important prognostic information but also allows for a coordinated imaging approach using angiography and aids localization of the bleeding...

The scintigraphic examination with Tc-99m pertechnetate-labeled anti-NCA 95 antigranulocyte antibodies (AGAb) was performed in a 14-year-old boy with a 7-year history of poorly controlled ulcerative colitis to estimate the spread and activity of the disease. The disturbance of the splenic function was also suspected because Howell-Jolly bodies were present in the peripheral blood smears. High A...

Meckel's diverticulum (MD) is estimated to affect 1%-2% of the general population, and it represents a clinically silent finding of a congenital anomaly in up to 85% of the cases. In adults, MD may cause symptoms, such as overt occult lower gastrointestinal bleeding. The diagnostic imaging workup includes computed tomography scan, magnetic resonance imaging enterography, technetium 99m scintigr...

Purpose: A nanoemulsion based gel containing Polyphenon 60 (P60) and cranberry (CRB) has been developed to deliver via intravaginal route for the treatment of urinary tract infection. Methods: Polyphenon 60 and cranberry were loaded in a single nanoemulsion gel (NBG) by ultra-sonication method and characterized for particle size, rheological properties, in vitro release and growth curve analysi...

OBJECTIVE Gastrointestinal motility and functional motility disorders causing either delayed or accelerated gastric emptying (GE) may result in similar symptoms including nausea, vomiting, early satiety, fullness, bloating, and abdominal discomfort or pain. Hence, it is important to evaluate patients for both rapid and delayed GE in the same test. The gold standard technique to measure GE is sc...

A 52-year-old woman presented with a small midline anterior neck mass and a 3-kg-weight loss over the course of one month. The patient was diagnosed with Graves disease based on increased free T4 levels (3.30 ng/dL), suppressed thyroid stimulating hormone (TSH) levels (<0.001 IU/mL), and a high titer of TSH receptor antibodies (32.6 IU/L). Scintigraphy with Tc-99m pertechnetate (Fig. 1) also re...
