The PET/CT was performed without complications. Evaluation of bile excretion over time was possible. 68Ga-TAoS-DAZA PET/CT may be an option for dynamic imaging of the excretory hepatic function to visualize the biliary tree and to rule out cholestasis.
The Toyota Production System (TPS) revolutionized automotive manufacturing and then spread more widely to other manufacturing and service industries, including healthcare. Many of the concepts in the TPS originated from ideas from the quality and production pioneers in the United States. Japanese experts built on these concepts and added many of their own to fashion them together into a comprehensive system. One of the key concepts in the TPS is to reduce waste without sacrificing quality.

A 48-year-old man presented with a painless enlarging mass on his right thigh for 2 months. He had a history of neurofibromatosis. MRI showed a mass in his right thigh. Malignant tumor was suspected. He was enrolled in the clinical trial of 68Ga-FAPI in solid tumors. Multiple increased FAPI uptake was observed in the right thigh mass, lung, and mediastinal lymph nodes, which were confirmed being pleomorphic rhabdomyosarcoma by biopsy. Sunitinib manufacturer In addition, widespread metabolic activity was also observed in his cutaneous fibroma nodules. This case showed that benign neurofibromatosis can cause FAPI uptake.

This article aims to explore the prognostic role of 18F-FDG PET/CT metabolic parameters in stage I lung adenocarcinoma patients.
One hundred eighty pathological stage I lung adenocarcinoma patients were retrospectively reviewed. Semiquantitative analysis of FDG tumor uptake was performed with TrueD software on the Siemens Leonardo workstation. SUVmean and MTV were calculated using SUV threshold of 41% of SUVmax; the total lesion glycolysis (TLG) was calculated as the product of SUVmean and MTV. Correlation was evaluated using Spearman correlation coefficient. Maximally selected rank statistics was performed to detect the optimal cutoff used for dichotomizing each PET parameter (6.5 for SUVmean, 9.6 for SUVmax, and 19.1 for TLG).
Our main finding was the significant correlation between 18F-FDG PET/CT parameters (SUVmean, SUVmax, and TLG) and disease-free survival in pathologic stage I non-small cell lung cancer. SUVmean has the greatest accuracy in recurrence prediction (integrated area under the curve, 0.803; 95% confidence interval, 0.689-0.918). We run the maximally selected rank statistics to provide the classification of observations in 2 groups by a continuous predictor parameter; the free from recurrence rate was significantly greater in patients with SUVmean ≤6.5, SUVmax ≤9.6, and TLG ≤19.1.
Our research supports the hypothesis that SUVmean, SUVmax, and TLG are well correlated with free from recurrence rate in stage I adenocarcinoma patients, subjected to pulmonary lobectomy. Our findings also indicate these markers as promising prognostic indicators.

We present a case of a 68-year-old woman undergoing 18F-choline PET/CT due to a history of hepatocellular cancer treated with multimodal therapies and with a rapid increase in α-fetoprotein. 18F-Choline PET/CT showed multiple uptakes in the skeletal muscles compatible with the recurrence of disease. The interpretation of 18F-choline PET/CT in this cancer should be careful and discussed in a multidisciplinary team.

A 71-year-old man underwent 68Ga-PSMA PET/CT for evaluation of a late biochemical recurrence after radical prostatectomy. An intense PSMA uptake was identified in spleen. Additional evaluation with a contrast-enhanced MRI showed a splenic lesion consistent with splenic hemangioma.

We report the case of 69-year-old man referred for a stage IV pulmonary adenocarcinoma and presenting a decrease in visual acuity. An 18F-FDG PET/CT showed an intense and heterogeneous uptake of a mass in the sellar region. An MRI showed a pituitary macroadenoma associated with a large cyst on the left side, with necrosis zones and fluid level, compressing the optic chiasma. Endocrine testing showed a panhypopituitarism, and pathology confirmed a pituitary apoplexy in a gonadotropin-secreting macroadenoma. No malignant cells were detected. Molecular imaging could have an important role in the detection and characterization of pituitary tumors.
