Gallium-67 scanning has been suggested as a means of diagnosing post-pericardiotomy syndrome. We have assessed the value of thoracic gallium scanning in patients with the post-myocardial infarction (Dressler's) syndrome, which is thought to have a similar pathogenesis. In five patients in whom the
Cerebral scans were obtained on 30 "stroke" patients first with 99mTc pertechnetate and subsequently with 67Ga citrate. Of the 26 patients with abnormal 99mTc static scans, 17 (65%) showed the same abnormality in gallium citrate scans also. In 4 patients with positive technetium flow studies but
This study was designed to evaluate the role and effectiveness of gallium 67 imaging in the diagnosis of acute myocarditis that mimics acute myocardial infarction. Of 315 consecutive acute myocardial infarction patients admitted to our institution over a 4-year period, 5 (2 men, 3 women) were
Clinical records and scintigrams were reviewed of 18 patients with sickle cell hemoglobinopathies who had undergone combined technetium and gallium scintigraphy during 22 separate episodes of suspected osseous infection. The combined scintigrams were correctly interpreted as indicating osteomyelitis
The authors describe the limited role of non-invasive imaging procedures in the differential diagnosis of splenic abscess versus infarction. Sonography and computed tomography often do not offer any characteristic findings in these splenic disorders. A case is reported as an example. By means of 111
The clinical records and scintigrams of patients with sickle hemoglobinopathy who underwent combined Tc-99m bone marrow imaging and Ga-67 imaging to differentiate osteomyelitis from bony infarction were reviewed. Of 18 paired examinations in 15 patients, osteomyelitis was diagnosed correctly in six
The appearance of gallium-67 images in bone infarction was studied in nine patients with sickle cell disease and correlated with the bone scan findings. Gallium uptake in acute infarction was decreased or absent with a variable bone scan uptake, and normal in healing infarcts, which showed increased
Scintigrams obtained 24 and 48 hours after the injection of 67Ga in a patient undergoing evaluation for fever of unknown origin revealed positive myocardial uptake. The subsequent clinical course, electrocardiograms, radionuclear studies, and postmortem examination confirmed a silent myocardial
Both 99mTc-pertechnetate and 67Ga-citrate brain scans were performed in 93 patients with cerebral neoplasms and in 70 others with cerebral infarction or hemorrhage. Tumor detection was clearly better with 67Ga(96%) than with 99mTc(85%). Cerebral infarctions consistently either failed to concentrate
A 66-year-old woman presented with vertigo and deafness. Diffusion-weighted magnetic resonance imaging of the head showed multiple cerebral infarctions involving several blood vessel regions. A diagnosis of cardiogenic embolism was made, and anticoagulation therapy was begun. The woman had no
OBJECTIVE
To determine the efficacy of sequential thallium and gallium scintigraphy to differentiate intracranial neoplasms (lymphoma and glioma) from other nonmalignant intracranial mass lesions among patients with acquired immunodeficiency syndrome (AIDS).
METHODS
The authors reviewed the cases of
Imaging of the chest cage with gallium-67 (67Ga) citrate is relatively easier to perform and interpret than imaging of the abdomen, because normally pulmonary concentration is low after 48 hr and physiologic accumulation in bones and breast can be recognized by its distribution. Modern scintillation
A four-and-a-half-month-old infant suffered sudden circulatory collapse early in the course of a brief febrile illness. The electrocardiogram initially appeared normal; an abrupt change indicative of extensive myocardial infarction occurred following stabilization. Coronary arterial anatomy and flow
