Efficacy of radionuclide scanning in patients with lung cancer.

Ninety-two patients with histologically proved carcinoma of the lung were studied retrospectively to determine the usefulness of liver, brain, and bone imaging in their examination and treatment. Occult metastatic liver disease was observed in two (5.3%) of 38 asymptomatic patients, while four (6.6%) of 58 neurologically intact patients had abnormal brain scans. Eight (13.6%) of 59 asymptomatic patients had metastatic bone disease. Seven (18.4%) of 38 patients with no clinical evidence of metastatic disease to liver, brain, or bone had at least one type of abnormal radionuclide study. More than half (52.5%) of the patients studied had at least one abnormal scan exclusive of symptoms. Radionuclide imaging is a useful procedure in the initial evaluation and subsequent management of lung cancer.

Nuclear imaging in urology.

Over the past 10 years nuclear renal imaging has proved to be a valuable diagnostic tool. The information derived from such studies must be correlated with all other imaging procedures now available, i.e., ultrasound and computed tomography. Prior to performing a study, the physician should focus carefully on what information is desired and whether or not it can be acquired. Once that is done, the use of these procedures in urology is extremely helpful and their aid in a given instance is limited only by the creative mind of the physicianuser.

Localization of 99mTc-Sn-pyrophosphate in left ventricular aneurysms.

Concentration of 99mTc-pyrophosphate (99mTc-PPi) in the area of left ventricular aneurysms is discussed. In three cases clinical, laboratory, and electrocardiographic (ECG) evidence did not indicate that these patients currently had an acute myocardial infarction, but each patient had a clinical history and an ECG picture compatible with an old myocardial infarction. Cardiac catheterization revealed a large left ventricular aneurysm in all three cases. The reason for the preferential uptake of the radionuclide in the area of these aneurysms is not certain at this time.
