Summary: This study aimed to evaluate the negative predictive value of PSMA PET scan for lymph node staging in patients who underwent robotic radical prostatectomy and pelvic lymph node dissection. The overall negative predictive value of PSMA PET scan was found to be 71.6%. However, further analysis based on risk stratification showed that the negative predictive value varied among different risk groups, with values of 58.02%, 92.7%, and 90% for high, intermediate, and low-risk patients, respectively.

Summary: This study evaluated the diagnostic accuracies of dual-time-point F-18-FDG PET/CT for detecting metastatic mediastinal lymph nodes in NSCLC patients. Results showed that dual-time-point F-18-FDG PET/CT exhibited good diagnostic performances for detecting metastatic mediastinal LNs, with retention index or %Delta SUVmax being superior to early or delayed images for detection of mediastinal LN metastasis.

Summary: In this high-risk PCa cohort, advanced disease was identified in about one third of patients at diagnosis. ISUP grade was found to be the superior predictor for advanced disease at diagnosis. A significant difference in frequency of advanced disease was observed between ISUP grades 2 and 3, supporting the Gleason score 7 subdivision. Interestingly, no significant differences in risk of advanced disease were found when comparing the different cT2 stages. The undetected LNMs were either PSMA-negative or micrometastases.

Summary: This study retrospectively reviewed 1445 F-18-DCFPyL PSMA PET/CT studies and found that the detection of non-prostate cancer tumors (NPCaT) using PSMA imaging was low. In contrast, atypical prostate cancer metastases showed intermediate to high PSMA expression.

Summary: F-18-DCFPyl is used to detect recurrent or metastatic prostate cancer and can target nonprostatic disease entities that mimic prostate cancer. The interpreting physician needs to consider serum prostate-specific antigen levels and uptake distribution to avoid misdiagnosis of metastatic prostate cancer. We describe the association of F-18-DCFPyl uptake with a previously undescribed hepatic small vessel neoplasm.

Summary: The study aimed to investigate whether the combined PET/CT radiomic features could predict lymph node metastasis of resectable NSCLC. A total of 192 NSCLC patients who underwent surgery and PET/CT scanning were included in this retrospective study. The results showed that the combination of CT and PET radiomic features could non-invasively predict lymph node metastasis in NSCLC, which may assist in developing more rational therapeutic strategies.

Summary: PSMA PET/CT has shown excellent results in imaging of prostate cancer, but nonprostatic malignancies, including primary lung cancer, can also demonstrate (18) F-PSMA uptake. In this case of a patient with concurrent metastatic prostate cancer, we observed different patterns of tumor uptake between primary lung cancer and lymph node metastases.

Summary: Differentiating lymph node metastases (LNM) from peripheral ganglia based on physiological prostate-specific membrane antigen (PSMA) uptake is challenging. Analyzing dual Ga-68-PSMA-11 and F-18-FDG PET-CT data from prostate cancer patients, it was found that the SUVmax of FDG-PET and PSMA-11-PET, especially when combined, could effectively differentiate LNM from ganglia. Differences in tracer uptake between cervical/coeliac and sacral ganglia should be taken into consideration during image assessment.

Summary: This study aimed to develop Convolutional Neural Networks (CNNs) to increase the signal-to-noise ratio (SNR) for low-count F-18-FDG and Zr-89-antibody PET scans. The CNNs showed higher tumor recovery coefficient (TRC) and comparable or lower coefficient of variance (COV) compared to Gaussian smoothing (GS) and Bilateral filtering (BF), and were preferred by two nuclear medicine physicians. The CNNs improved the SNR of low-count F-18-FDG and Zr-89-rituximab PET with similar or better clinical performance than full-count PET.

Summary: Extensive angiogenesis in rheumatoid arthritis is a crucial event in the development of proliferative synovium and can be influenced by disease duration, activity, severity, and inflammatory cell infiltration. Nuclear imaging modalities are valuable tools for accurately tracking molecular changes in angiogenesis in multiple joints simultaneously.

Summary: This study assessed the sensitivity of different image reconstruction methods on various metabolic tumor volume (MTV) segmentation methods and the ability of ComBat to improve the reproducibility of MTVs. The results showed that the SUV4.0 method was the least sensitive to different reconstructions, and after using ComBat for harmonization, most segmentation methods showed improved agreement in MTVs among different reconstructions. The study also found that the version of ComBat using log-transformed datasets was more accurate and precise compared to the version using non-transformed distributions.

Summary: Currently, guidelines for PET with FDG-PET interpretation for therapy response in oncology involve visual evaluation of FDG-PET/CT scans. However, quantitative measurements of metabolic activity in tumors may be more useful. Guidelines based on such measurements have been proposed, but more analysis is needed for regular use.

Summary: The objective of this study is to validate and compare the clinical PET model developed in the HOVON-84 trial with the international prognostic index (IPI) in DLBCL patients. A total of 1195 patients were included, and data from 6 studies were used as external validation. The clinical PET model showed higher predictive values and model performance compared to the IPI. The clinical PET model remained predictive of outcome in 6 independent DLBCL studies and outperformed the currently used IPI.

Summary: This study evaluated the additional value of prostate-specific membrane antigen positron emission tomography (PSMA-PET) compared to conventional diagnostic tools for selecting patients for hemi-ablative focal therapy (FT). The results showed that by combining PSMA-PET with multiparametric magnetic resonance imaging (mpMRI) and systematic biopsies, the accuracy of selecting potential candidates for hemi-ablative FT was significantly improved.

Summary: We developed a prognostic model for progression-free survival (PFS) in patients with relapsed or primary refractory classical Hodgkin lymphoma (R/R cHL) using baseline quantitative F-18-fluorodeoxyglucose positron emission tomography (PET) radiomics features and clinical characteristics. The model can help predict PFS outcomes and guide risk-stratified treatment strategies for R/R cHL patients.

Summary: The current diagnostic criteria for myelofibrosis are limited by sampling errors in bone marrow (BM) biopsies. Explorative studies have suggested imaging as an alternative for evaluating disease activity, but the choice of optimal technique is complicated due to heterogeneity in BM abnormalities. This prospective diagnostic pilot study used PET/CT and MRI to visualize all BM abnormalities in myelofibrosis before and during ruxolitinib treatment.
