Medicine of all the branches of science has lagged behind the power curve in ages past and is doing so again in the era of information, frequently using the excuse that medicine is an art than a ...science. In alarming contrast, the general population has come to expect immediacy in all aspects of life as well as death. They are clearly frustrated with the inability of purveyors of healthcare to answer their need for immediacy and resolution. This manifests itself in the increasing diatribe against health maintenance organizations and the growth in tort claims, the widening chiasm between the healthcare providers and their beneficiaries.
Three case reports of spinal vascular tumors illustrate the need for well-organized and thorough neuroradiological and neurosurgical planning to achieve an initial cure without delay and to avoid ...inadequate operative procedures.
Four methods of Tc-99m red blood cell labeling were tested for labeling efficiency and kinetics in normal adults. From a perspective of the gastrointestinal hemorrhage study, the in vivo method was ...least appropriate because of extravascular loss of pertechnetate. The modified in vitro method was disadvantageous because of long labeling intervals in a syringe fixed to the patient's forearm (45 minutes). The pure in vitro methods produced the highest labeling efficiency (95% +) and are preferred by the authors.

A new cholescintigraphic finding, the "hot rim" sign, is reported in a case of acute cholecystitis. Local inflammation in the gallbladder fossa may be the cause of this phenomenon.
The differential diagnosis of a solitary photopenic defect in the renal fossa observed at renal scintigraphy is extensive. A case of one of the most unusual causes for this finding, renal agenesis, ...is presented. Additional cases that illustrate the similarity in the radionuclide appearance of other pathologic entities are also presented. Correlation with clinical findings and other imaging modalities is required to accurately distinguish these conditions.
The authors report a case of "hot spot" localization on SPECT hepatic scintigraphy secondary to IVC obstruction. The tomographic slices demonstrated the location of the focal increase in radiotracer ...activity as anterior, within the medial segment of the left lobe of the liver. Radionuclide angiography confirmed the extensive collateral vasculature of IVC obstruction.
