Adrenal washout CT in patients with no history of cancer: a waste of time?
ConclusionOur study validates a recent report suggesting that adrenal washout has poor sensitivity for and consequent limited utility to exclude malignancy in patients with no cancer history. However, patients with incidental adrenal nodules  <  4 cm in size with benign washout can be reassured by the high negative predictive value and worked up to exclude functional adenoma and re-imaged in a year to confirm no growth.Graphical Abstract (Source: Abdominal Imaging)

Standardizing technical parameters and terms for abdominopelvic photon-counting CT: laying the groundwork for innovation and evidence sharing
AbstractPhoton-counting detector CT (PCD-CT) is a new technology that has multiple diagnostic benefits including increased spatial resolution, iodine signal, and radiation dose efficiency, as well as multi-energy imaging capability, but which also has unique challenges in abdominal imaging. The purpose of this work is to summarize key features, technical parameters, and terms, which are common amongst current abdominopelvic PCD-CT systems and to propose standardized terminology (where none exists). In addition, user-selectable protocol parameters are highlighted to facilitate both scientific evaluation and early clinical a...

Role of imaging in evaluating the complications of endoscopic management of pancreatic fluid collections in acute pancreatitis
AbstractAcute pancreatitis is associated with local and systemic complications. Pancreatic fluid collection (PFC) is the most common local complication. Infected or symptomatic PFCs need drainage. Endoscopic drainage (ED) is the first-line procedure for accessible PFCs adjacent to the stomach and duodenum. ED is performed under endoscopic ultrasound (EUS) guidance. The technical and clinical success rates of EUS-guided ED in well-encapsulated PFCs are high. ED of poorly encapsulated PFCs is associated with complications. Bleeding and perforation are the most common complications. Contrast-enhanced computed tomography is cr...

Ultrasound of palpable lesions: a pictorial review
AbstractUltrasound (US) is the imaging modality of choice for evaluation of superficial palpable lesions. A large proportion of these lesions have characteristic sonographic appearance and can be confidently diagnosed with US without the need for biopsy or other intervention. The Society of Radiologists in Ultrasound (SRU) recently published a Consensus Conference Statement on superficial soft tissue masses. The goal of this manuscript is (a) to serve as a sonographic pictorial review for palpable lesions based on the SRU statement, (b) present the typical sonographic features of palpable lesions that can be confidently di...

Early detection of pancreatic cancer in the era of precision medicine
AbstractPancreatic ductal adenocarcinoma (PDAC) is the third leading cause of cancer-related mortality and it is often diagnosed at advanced stages due to non-specific clinical presentation. Disease detection at localized disease stage followed by surgical resection remains the only potentially curative treatment. In this era of precision medicine, a multifaceted approach to early detection of PDAC includes targeted screening in high-risk populations, serum biomarkers and “liquid biopsies”, and artificial intelligence augmented tumor detection from radiologic examinations. In this review, we will review these emerging ...

Is the excretory phase necessary to identify upper tract urothelial neoplasms at CT urography? A 10-year population-based study
ConclusionIn our population, almost all UTUCs were evident via primary or secondary imaging findings without requiring the excretory phase. These results support streamlining protocols and pathways. (Source: Abdominal Imaging)

MRI of pelvic endometriosis: evaluation of the mr#Enzian classification and the importance of adenomyosis subtypes
ConclusionsThe mr#Enzian showed mostly high inter-reader agreement and good diagnostic accuracy for various endometriosis compartments. MRI ’s role is particularly significant in the context of the current paradigm shift towards medical endometriosis treatment. The inclusion of information about the type of adenomyosis in the mr#Enzian classification could enhance diagnostic accuracy and inform treatment planning.Graphical Abstract (Source: Abdominal Imaging)
