Macroaggregates of albumin labeled with 99mTc and 131I were injected into the coronary arteries in 400 patients undergoing coronary arteriography. The three major coronary artery systems were divided into six groups, based upon coronary arteriography

1. The transverse thoracis muscle produces a variable retrosternal density in the lateral chest roentgenogram.2. Its roentgen appearance is determined by: (a) Position of the patient; (b) portion of the muscle visualized; and (c) contrast of tissue s

The Roentgenographic differential diagnosis of solitary lung nodules is a difficult problem (3). In a significant group of patients the roentgen findings are virtually nonspecific, while in other cases the radiologist feels confident in making a spec

The determination of myocardial viability is a crucial parameter in the evaluation of a patient with coronary artery disease. Particulate myocardial perfusion scintigraphy (PMPS) is one of several methods available for this determination. A brief com

Fast quantitative dynamic studies with scintillation camera systems require deadtime correction. Although such systems are semiparalyzable, they are most conveniently treated either as paralyzable or nonparalyzable. Paralyzing deadtime (τ) is that d

Medical radioisotope scintigrams are most commonly produced as photographic images in which count densities are displayed in various shades of grey. Such photographic grey scales are used both for recording the live images from a rectilinear scanner

The estimation of serum vitamin B12 is frequently required in the work-up of megaloblastic anemias. The procedure of choice—although it has not proved to be accurate—has been a microbiological assay (3) which takes from two to five days to comple

Two patients who had hypercalcemia, one from multiple myeloma and the other from metastatic carcinoma, showed striking concentrations of bone-seeking radiopharmaceuticals in the lungs on routine bone scans. Neither patient had roentgenographic eviden
