[en] This paper reports twenty-five MR and twenty Ga-67 citrate examinations obtained in 10 patients with lymphoma compared as to their value in detecting sites of abnormality and assessing interval changes after therapy. MR and Ga-67 studies were equally sensitive for sites of abnormality in the chest. MR was more sensitive for sites of abnormality in the abdomen. There was a generally parallel trend toward normality in Ga-67 and MR studies following therapy. However, abnormalities on Ga-67 scans converted to normal sooner after therapy than did MR abnormalities in some patients

[en] This paper identifies pancreatic tumors with positron emission tomography (PET) using F-18 2-fluorodeoxyglucose (FDG). PET studies were performed in 13 patients with pancreatic tumors (11 adenocarcinomas; two islet cell tumors) using FDG. Data were acquired for 1 hour and in 14 contiguous 7-mm sections after attenuation correction. Suspicious areas were evaluated using quantitative techniques. In seven of 11 patients with adenocarcinomas, focal increase in FDG uptake correlated with pancreatic tumor shown on CT scans or MR images. Of the remaining four, one had a previous Whipple procedure, another had completed chemotherapy, and in two the tumor was out of the limited region imaged; in these four patients, liver metastases were identified in three
