A 32-year-old man presented with palpitation. He was diagnosed with pulmonary sarcoidosis by lung biopsy. The electrocardiogram showed first-degree atrioventricular block and complete right bundle branch block (CRBBB). We planned to examine laboratory data, echocardiography, Holter monitoring, and gallium-67 scintigraphy. Before he went through all these exams, he developed ventricular tachycar...

OBJECTIVE Although the use of 18F-fluorodeoxyglucose (FDG) PET for evaluating lymphoma is gaining in popularity, PET is not yet universally available and large prospective comparisons between 67Ga and 18F-FDG PET scans in predicting the long-term outcome after treatment are lacking. Scintigraphic imaging with 67Ga remains an important tool in evaluating the response of lymphoma to therapy. Ther...

A 32-year-old woman was admitted to our hospital with fever and shoulder pain. Gallium-67 scintigraphy revealed uptake in the anterior chest region corresponding to the descending thoracic aorta (Picture 1). Although the findings of enhanced magnetic resonance imaging (MRI) and MRI angiography appeared normal, the scintigraphy results indicated a diagnosis of early Takayasu’s arteritis (TA). Fo...

Thirty two patients with persisting pulmonary sarcoidosis fulfilling defined criteria for treatment were managed according to a standard clinical protocol. In this an attempt was made to achieve and maintain maximal radiographic and physiological improvement with individually titrated doses of corticosteroids. Lavage cell counts, serum angiotensin converting enzyme (SACE) determinations, and ga...

Atypical mycobacterium is rarely seen as a cause of chronic mastoiditis but has been increasingly recognized over the past few years. Mycobacterium abscessus is the most pathogenic and chemotherapy-resistant, rapid-growing mycobacterium of all the four groups. This paper presents a case of a 57-year-old woman who had chronic mastoiditis with recurrent exacerbations. The initial computed tomogra...

An 18-year-old man was admitted to our hospital for further examination of fever of unknown origin and ascites. Ga-67 scintigraphy revealed diffuse increased uptake throughout the abdomen. He was diagnosed with tuberculous peritonitis and began the treatment for tuberculosis (rifampicin, 450 mg/day orally and isoniazid, 300 mg/day orally, and 0.75 g of streptomycin by intramuscular injection 2 ...

Titanium-doped gallium lanthanum sulfide (Ti:GLS) and gallium lanthanum oxysulfide (Ti:GLSO) glasses have an absorption band at 500–600 nm that cannot be fully resolved because of its proximity to the band edge of the glass. At concentrations 0.5% a shoulder at 980 nm is observed in Ti:GLS but not in Ti:GLSO. The emission spectra of Ti:GLS and Ti:GLSO both peak at 900 nm with lifetimes of 67 an...

INTRODUCTION Despite its desirable half-life and low energy Auger electrons that travel further than for other radionuclides, 67Ga has been neglected as a therapeutic radionuclide. Here, 67Ga is compared with Auger electron emitter 111In as a potential therapeutic radionuclide. METHODS Plasmid pBR322 studies allowed direct comparison between 67Ga and 111In (1MBq) in causing DNA damage, includ...

This is the first in a series of four continuing education articles on AIDS patient management and care. This article is designed to present an overview of complications due to the AIDS virus and the use of nuclear medicine techniques to assist in patient management. Upon completion of this article the technologist will be able to: I) identify complications due to the AIDS virus,· 2) recognize ...
