Preoperative imaging accuracy in size determination of prostate cancer in men undergoing radical prostatectomy for clinically localised disease
ConclusionsSize measurement of prostate cancers on preoperative imaging utilising maximum linear extent technique, underestimated the extent of cancer. Further research is needed to confirm our observations using different sequences, methods and approaches for cancer size measurement. (Source: Insights into Imaging)

A virtual biopsy study of microsatellite instability in gastric cancer based on deep learning radiomics
ConclusionsUsing preoperative imaging and clinical information, we developed a deep-learning-based radiomics model for the non-invasive evaluation of MSI in GC patients. This model maybe can potentially support clinical treatment decision making for GC patients.Graphical abstract (Source: Insights into Imaging)

Retrospective batch analysis to evaluate the diagnostic accuracy of a clinically deployed AI algorithm for the detection of acute pulmonary embolism on CTPA
ConclusionThe AI algorithm showed a significantly higher diagnostic accuracy for the detection of PE on CTPA compared to the report of the attending radiologist. This finding indicates that missed positive findings could be prevented with the implementation of AI-assisted reporting in daily clinical practice.Critical relevance statementMissed positive findings on CTPA of patients suspected of pulmonary embolism can be prevented with the implementation of AI-assisted care.Key pointsThe AI algorithm showed excellent diagnostic accuracy detecting PE on CTPA.Accuracy of the AI was significantly higher compared to the attending...

Acute abdominal pain in women of reproductive age: keys to suggest a complication of endometriosis
AbstractAlthough endometriosis is a common gynecological condition in women of reproductive age, a complication of endometriosis is rarely considered as the differential diagnosis of acute abdominal pain in that context. However, acute events in women with endometriosis can represent life-threatening conditions, which require emergent treatment and often surgical management. Mass effect of endometriotic implants can give rise to obstructive complications, specifically occurring in the bowel or in the urinary tract, while inflammatory mediators released by ectopic endometrial tissue can lead to inflammation of the surroundi...

Short-term PET-derived kinetic estimation for the diagnosis of hepatocellular carcinoma: a combination of the maximum-slope method and dual-input three-compartment model
ConclusionsShort-term PET is closely equivalent to fully dynamic PET for liver kinetic estimation. Short-term PET-derived kinetic parameters can be used to distinguish HCC from background liver tissue, and the combined model improves the kinetic estimation.Clinical relevance statementShort-term PET could be used for hepatic kinetic parameter estimation. The combined model could improve the estimation of liver kinetic parameters.Graphical Abstract (Source: Insights into Imaging)

Three-dimensional multifrequency magnetic resonance elastography improves preoperative assessment of proliferative hepatocellular carcinoma
ConclusionsProliferative HCC exhibits low stiffness and high fluidity. Adding MRE properties (tumorc and tumorφ) can improve performance of conventional MRI for preoperative diagnosis of proliferative HCC.Critical relevance statementWe investigated the viscoelastic signatures of proliferative hepatocellular carcinoma (HCC) using three-dimensional (3D) magnetic resonance elastography (MRE), and find that adding MRE properties (tumor c and tumorφ) can improve performance of conventional MRI for preoperative diagnosis of proliferative HCC.Graphical Abstract (Source: Insights into Imaging)
