Summary: This study investigates the ability of F-18-AlF-NOTA-PRGD2 positron emission tomography/computed tomography (F-18-RGD PET/CT) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) to predict the response to bevacizumab combined with conventional therapy in newly diagnosed glioblastoma patients. The results show that a greater decrease in SUVmean predicts better progression-free survival (PFS), while a small decrease in K-trans predicts improved overall survival (OS).

Summary: Hibernomas are rare benign tumors originating from fetal brown adipose tissue. They can occur in various parts of the body, with thigh, shoulder, back, and neck being the most common locations, and are rarely found in the abdominal cavity, retroperitoneum, breast, bones, scrotum, and perirectum. We present a case of a 58-year-old woman with a mediastinal mass, who was incidentally found to have an FDG-avid fat-containing lesion in the omentum abutting the stomach.

Summary: This study aimed to improve the statistical power in detecting changes in brain glucose metabolism, amyloid, and tau deposition in Alzheimer's disease studies by using a reference tissue-based quantification approach. The results showed that the tracer-specific reference tissue improved the detection of PET SUVR changes, which is beneficial for early diagnosis, disease progression monitoring, and therapeutic response in Alzheimer's disease.

Summary: This study investigated the value of F-18-FDG PET/MRI in the preoperative assessment of ESCC and compared it with other imaging methods. The results showed that F-18-FDG PET/MRI had higher accuracy and area under the curve in diagnosing primary tumors and regional lymph node metastases. Therefore, F-18-FDG PET/MRI may be a potential supplement or alternative imaging method for preoperative staging of ESCC.

Summary: F-18-FDG PET/MRI is superior to conventional imaging and MRI in nodal staging in patients with newly diagnosed breast cancer. It accurately detects nodal positive status and classifies it into the correct clinical lymph node stage more often. F-18-FDG PET/MRI has the potential to be an alternative to invasive staging procedures for assessing the N stage.

Summary: This study evaluated the diagnostic accuracies of F-18-FDG PET or PET/CT for Merkel cell carcinoma (MCC) through a systematic review and meta-analysis. The results showed that F-18-FDG PET/CT had excellent performance in diagnosing MCC and could be useful for exclusion and confirmation of the disease. Further large multicenter studies are needed to validate its diagnostic accuracy.

Summary: A 15-year-old boy presented with left body epilepsia partialis continua, hemiparesis, and right hemisphere dominant electroencephalogram abnormalities. MRI revealed a small hyperintense signal in the left putamen. F-18-FDG PET showed focal glucose hypermetabolism in the right paracentral lobule and hypometabolism in the inferior right frontal and precentral gyri. A subsequent MRI showed a hyperintense signal over the paracentral lobule, which was confirmed as Rasmussen encephalitis by biopsy. The patient underwent right hemispherotomy and achieved seizure freedom. This case highlights the importance of PET in the early diagnosis of Rasmussen encephalitis.

Summary: A 76-year-old man with yellowish discoloration of sclera and skin for 2 months was referred for F-18-FDG PET/CT to characterize a mass in the pancreas. PET/CT images showed intense FDG uptake in the head of the pancreas, with a lymph nodal mass in the hepatic hilar region, consistent with pancreatic malignancy. Histopathologic findings confirmed diffuse large B-cell lymphoma with no evidence of adenocarcinoma.

Summary: This study explored the combination of F-18-FDG and F-18-Alfatide II in predicting molecular subtypes of invasive breast cancer using noninvasive PET molecular imaging. The results suggest that the combination of F-18-FDG and F-18-Alfatide II, as represented by FAR, can be used to predict molecular subtypes of invasive breast cancer, particularly the luminal B (HER2 negative) subtype and the nonluminal subtype.

Summary: This meta-analysis compared the diagnostic efficacy of [F-18]FDG PET/CT and [F-18]FDG PET/MRI in detecting bone metastases in breast cancer patients. The results showed that [F-18]FDG PET/MRI has higher sensitivity but similar specificity compared to [F-18]FDG PET/CT. Further prospective research is needed to confirm these findings and evaluate the clinical application of these techniques.

Summary: This article presents a rare case of primary malignant mesothelioma in the liver, with the patient being a 48-year-old woman who experienced increasing upper abdominal discomfort and inappetence, accompanied by a weight loss of approximately 10 kg. CT and MRI revealed a highly suspicious mass lesion in the liver. F-18-FDG PET/CT performed for staging showed a pathological F-18-FDG uptake of the known liver tumor. Histology and immunohistochemistry indicated mesothelioma of the liver.

Summary: A mathematical model was developed to describe the kinetics of Pb-212-labeled pharmaceuticals and its radioactive daughters. The simulation revealed that alpha emissions contributed significantly to the total released energy, and the Bi-212-DOTAM complexes had a certain dissociation during retention. The contributions of different chelators to the energy released by free radionuclides were varied.

Summary: This study demonstrated the feasibility of noninvasive imaging of fibroblast activation protein (FAP) expression after myocardial infarction (MI) using Ga-68-FAPI-04-PET, and showed that Ga-68-FAPI-04 uptake extends beyond the actual infarcted area in the infarct territory. Follow-up CMR confirmed the overestimation of the infarct size by Ga-68-FAPI-04 uptake.

Summary: The purpose of the study was to assess (68) Ga-fibroblast-activation protein inhibitor (FAPI) uptake in the pulmonary vein region after pulmonary vein isolation (PVI) with cryoballoon ablation (CBA) and radiofrequency (RFA). The results showed higher FAPI uptake in PVs in PVI patients compared to controls, and CBA seemed to cause more pronounced fibroblast activation following tissue injury than RFA. Future studies are needed to further understand the mechanisms of AF recurrence after PVI.

Summary: This study investigated the impact of different cardiac gating methods on the assessment of cardiac function using FDG-PET. The results showed that the PET and MR-based cardiac function parameters were highly correlated, but the selected PET ECG gating method introduced variabilities and led to substantial disagreement in the assessment.

Summary: It is shown that the steady state of rapid TR-periodic SSFP sequences at small to moderate flip angles follows a universal scaling law with respect to variations of B-1(+). The accuracy and precision of relaxometry experiments are discussed through analytical solutions, Cramer-Rao bound, and Monte Carlo simulations. Simultaneous estimation of R-1 and B-1(+) from SSFP steady states alone is not recommended, and additional transient state information is needed to address the issue.

Summary: In this retrospective study, MRI and CT were compared in patients with recurrent DTC. The results showed that MRI performed better in evaluating cervical recurrence, while CT performed better in evaluating lung lesions. Therefore, PET/MRI combined with low-dose CT may be the ideal staging tool for patients with recurrent DTC.

Summary: Noninvasive imaging techniques, such as SPECT, PET, CT, echocardiography, or MRI, have become essential in cardiovascular research and offer numerous advantages, such as high sensitivity and reliable quantification. Incorporating SPECT and PET imaging into a well-defined workflow similar to clinical imaging can effectively implement the concept of bench to bedside in cardiology translational research.

Summary: The CAM model shows promise as an alternative to mouse models in terms of the 3Rs principles. However, further evaluation is needed to determine its value in noninvasive assessment of radiolabeled macromolecules using PET and MRI. This study analyzed the biodistribution and tumor accumulation of Zr-89-labeled albumin in both CAM and mouse models, and found no significant differences in albumin influx kinetics between the two models. These findings suggest that the CAM model could be a potential alternative for initial PET studies on the characteristics of EPR-dependent target accumulation of radiolabeled macromolecules.
