Predicting resection margin status of pancreatic neuroendocrine tumors on CT: Performance of NCCN resectability criteria
CONCLUSIONS: NCCN resectability criteria can stratify patients with PNET into distinct groups of R0 resectability. Adding tumor size to R disease substantially improves the prediction of R0 resection, especially for PNETs < 2 cm.ADVANCES IN KNOWLEDGE: Tumor size and radiologic resectability independently predicted margin status of PNETs.PMID:37750830 | DOI:10.1259/bjr.20230503 (Source: The British Journal of Radiology)

Medical imaging applied to heritage
Br J Radiol. 2023 Sep 26:20230611. doi: 10.1259/bjr.20230611. Online ahead of print.ABSTRACTThe use of imaging has transformed the study of cultural heritage artefacts in the same way that medical imaging has transformed medicine. X-ray based techniques are common in both medical and heritage imaging. Optical imaging, including scientific photography and spectral imaging techniques, is also common in both domains. Some common medical imaging methods such as ultrasound and MRI have not yet found routine application in heritage, whereas other methods such as imaging with charged and uncharged particles and 3D surface imaging...

The utility of [ < sup > 18 < /sup > F]Fluciclovine PET/CT in Evaluating Nonmetastatic Castrate Resistant Prostate Cancer Patients (nmCRPCp): Diagnostic performance and Impact on Management
CONCLUSION: Detecting the source of recurrence is challenging in nmCRCP patients when conventional imaging fails. Given the high PPV, sensitivity, and specificity, [18F]Fluciclovine PET/CT can be used instead of conventional imaging as a first-line choice due to its superiority over bone scan and added value of detecting soft tissue metastasis regardless of the initial Gleason score.ADVANCES IN KNOWLEDGE: The study highlights the added value of [18F]Fluciclovine PET/CT in detecting soft tissue metastasis regardless of the initial Gleason score, which is not possible with conventional imaging such as bone scans.The study hi...
