PET/CT SKULL TO MID THIGH INT TX 78815PI - Final
Result/Status Change: INDICATION: Lung cancer. 162. Colon cancer. 153.9 evaluate extent of disease. TECHNIQUE: Approximately 60 minutes following injection 11 mCi F-18 FDG, PET/CT imaging performed from the base of skull to the mid thighs. Study is performed utilizing images in attenuated and not attenuated corrected modes. Images are reviewed on a workstation in sagittal, axial and coronal views and MIP image. Study is done in conjunction with a CT examination primarily for purposes of anatomic correlation and for attenuation correction but also for diagnostic interpretation. Oral contrast administered. Patient had a fasting blood glucose of 196 mg/dL. COMPARISON: none FINDINGS: Unremarkable FDG uptake is seen in the visualized brain. There is no evidence of FDG avid lymphadenopathy in the neck. Physiologic FDG uptake is seen in the thyroid gland. Evaluation of the thorax performed. Pulmonary reticular interstitial disease with subpleural fibrosis is seen. Motion degrades imaging of the lungs. Subpleural ill-defined nodular opacity noted within the lateral left upper lung lobe (series 3, image 145), 1.5 cm, which has slightly increased FDG uptake, with maximum standard uptake value ( SUV max) 2.3. Anterior left upper lung lobe 9 mm (image 158) and 1.7 cm (image 177) nodular densities are seen which without significant increased FDG uptake compared to the surrounding lung. Right upper lung lobe subpleural nodular densities are seen largest measuring 2 cm (image 142), without significant increased FDG uptake compared to the surrounding lung. There is no evidence of a pericardial or pleural effusion. Enlarged mediastinal lymph nodes with FDG uptake isointense to the mediastinal soft tissues (not significantly FDG avid) are seen in the precarinal, prevascular, posterior right para-esophageal regions measuring up to 1.4 cm in short axis diameter. There is no evidence of hilar lymphadenopathy. Unremarkable FDG uptake is seen within the breasts. There is no evidence of axillary lymphadenopathy. Evaluation of the abdomen and pelvis performed. Unremarkable FDG uptake is seen in the liver parenchyma. There is no evidence of an FDG avid liver mass. The gallbladder, pancreas, spleen, right adrenal gland and left adrenal gland appear unremarkable with physiologic FDG tracer localization. IVC unremarkable. Calcified atheromatous plaquing noted of the aorta. No aortic aneurysm. Right kidney, left kidney, renal collecting systems and urinary bladder have physiologic FDG tracer localization. Prostate gland and seminal vesicles have unremarkable FDG uptake. The stomach, small and large bowel have physiologic FDG uptake. Mild diverticulosis is seen of the colon. There is no evidence of FDG avid lymphadenopathy. Evaluation of the musculoskeletal structures performed. There is no evidence of FDG avid osseous malignancy. Degenerative arthropathy noted in the dorsal spine. IMPRESSION: Pulmonary interstitial disease and fibrosis. Ill-defined pulmonary nodular densities are seen with mild increased FDG uptake or without significant increased FDG uptake which are possibly due to benign infectious inflammatory disease. Enlarged non-FDG avid mediastinal lymphadenopathy is seen of nonspecific etiology possibly due to infectious or inflammatory disease versus hypometabolic/low-grade malignant neoplasia. There is no evidence of FDG avid metastatic malignancy in the abdomen or pelvis or skeletal structures. Read by: VADDE, KAVITHA , MD |
