One hundred eighty-seven patients who presented with symptoms consistent with biliary colic but had no ultrasonic evidence of cholelithiasis were observed in an effort to identify those with a functional gallbladder disorder that might benefit from surgical intervention. All patients underwent quantitative evaluation of gallbladder emptying using cholecystokinin biliary scanning, and ejection fractions less than 35% were considered abnormal. One hundred twenty-nine patients (69%) had abnormal ejection fractions, and 88 (68%) of these subsequently underwent cholecystectomy. Sixty of the surgical specimens revealed pathologic changes. Eighty-four percent of patients successfully contacted for follow-up experienced complete relief, and another 13% had partial relief of preoperative symptoms. Only two patients reported no change in symptom complex. Twenty-nine patients with abnormal ejection fractions elected not to undergo surgery. Fifty-nine percent of these patients continued to experience symptoms of biliary colic at a mean follow-up of 22 months. Of the 44 patients with normal ejection fractions, 35 (80%) reported resolution of symptoms during follow-up of medical treatment. Cholecystokinin biliary scanning can help identify patients with acalculous, functional gallbladder disease who may benefit from cholecystectomy.

Distinct quantum metabolic values of -1 and 0 were noted in NHL. Aggressive NHL has a more negative value (or higher glucose sensitivity) than that of indolent and, thus, is more susceptible to extreme glucose variation.

Results suggest that there is significant mean reduction of hepatic metastatic tumor load (metabolism), as evaluated objectively by PET after Y-90 microsphere, for the treatment of unresectable metastatic disease to the liver. The Y-90 therapy provides encouraging and safe results by arresting the progression of metastatic cancer to the liver with decreasing tumor metabolism.

The incidental detection of an hepatic cavernous hemangioma may create a problem in differential diagnosis. The authors here review the characteristics of hemangiomas as recorded by various types of imaging.
