FDG-PET accurate for evaluating lung tumor destruction from radiofrequency ablation
FDG-PET can be used to assess the amount of tumor destruction after radiofrequency ablation (RFA)--the use of heat to destroy tumors--for the treatment of lung tumors and may provide more valuable information than CT alone, according to a new study....... For the study, researchers assessed 10 tumors in 10 patients who had lung tumors treated with CT-guided RFA and had PET scans both prior to RFA...MRI better than FDG PET at detecting liver tumors
Significantly more and smaller liver tumors can be detected by contrast-enhanced MRI when compared to whole-body FDG PET, say researchers from Massachusetts General Hospital in Boston....... For the study, the researchers analyzed 79 liver tumors in 30 patients. MRI detected all 79 of the lesions, of which 33 were less than 1 cm. PET detected 65 lesions, of which only 12 were less than 1 cm. In a...Bone SPECT superior to FDG PET for detecting bone metastases in breast cancer
Bone SPECT is better than FDG PET for detecting breast cancer that has spread (metastasized) to a patient's bones, according to researchers from Shizuoka Cancer Center Hospital in Japan....... FDG PET is an imaging technique based on the increased metabolism of glucose in tumor cells. SPECT is a...type of nuclear medicine scan that detects special radioactive elements administered to the patient...
