CT and MR imaging of the properitoneal fat pad: a pictorial essay
AbstractThe properitoneal fat pad is a distinctive anatomical structure located in the midline of anterior abdominal wall between the transversalis fascia and parietal peritoneum. It has variable size and configuration depending on the gender and nutritional status of individuals, but CT and MR images of the upper abdomen can readily depict its shape and adipose composition. The purpose of this essay is to illustrate the CT and MRI features of normal properitoneal fat pad, and the spectrum of pathological processes that affect it among patients. This information can be relevant to the practicing radiologists and clinicians...

Image quality optimization: dynamic contrast-enhanced MRI of the abdomen at 3T using a continuously acquired radial golden-angle compressed sensing acquisition
ConclusionOur study demonstrated that the optimized scheme significantly improved the image quality of liver DCE-MRI with GRASP sequence both in plain and arterial phases. The optimized scheme of GRASP sequence could be a superior alternative to conventional approach for the assessment of liver. (Source: Abdominal Imaging)

Imaging advances in efficacy assessment of gastric cancer neoadjuvant chemotherapy
AbstractEffective neoadjuvant chemotherapy (NAC) can improve the survival of patients with locally progressive gastric cancer, but chemotherapeutics do not always exhibit good efficacy in all patients. Therefore, accurate preoperative evaluation of the effect of neoadjuvant therapy and the appropriate selection of surgery time to minimize toxicity and complications while prolonging patient survival are key issues that need to be addressed. This paper reviews the role of three imaging methods, morphological, functional, radiomics, and artificial intelligence (AI)-based imaging, in evaluating NAC pathological reactions for g...

Predicting response to chemoradiotherapy in rectal cancer via visual morphologic assessment and staging on baseline MRI: a multicenter and multireader study
ConclusionsVisual morphologic assessment and staging methods can predict neoadjuvant treatment response with moderate–good performance. Compared to a previously published confidence-based scoring system, study readers preferred a simplified 4-point risk score based on high-risk T-stage, MRF involvement, nodal involvement, and EMVI.Graphical abstract (Source: Abdominal Imaging)

Gynecologic oncology tumor board: the central role of the radiologist
AbstractThis manuscript is a collaborative, multi-institutional effort by members of the Society of Abdominal Radiology Uterine and Ovarian Cancer Disease Focus Panel and the
European Society of Urogenital Radiology Women Pelvic Imaging working group. The manuscript reviews the key role radiologists play at tumor board and highlights key imaging findings that guide management decisions in patients with the most common gynecologic malignancies including ovarian cancer, cervical cancer, and endometrial cancer.

Can 1.25 mm thin-section images generated with Deep Learning Image Reconstruction technique replace standard-of-care 5 mm images in abdominal CT?
ConclusionDLIR allows generation of thin-section (1.25 mm) abdominal CT images, which provide improved image quality with higher inter-reader agreement compared to 5 mm thick images reconstructed with ASIR-V.Clinical ImpactImproved image quality of thin-section CT images reconstructed with DLIR has several benefits in clinical practice, such as improved diagnostic performance without radiation dose penalties.Graphical Abstract (Source: Abdominal Imaging)

Factors associated with increased risk of peritoneal seeding after radiofrequency ablation for hepatocellular carcinoma
ConclusionPeritoneal seeding after RFA is a rare, delayed complication. Subcapsular-located and viable HCC after previous locoregional treatment are potential risk factors for seeding. Seeding metastases could affect the prognosis of patients who cannot receive local therapy.Graphical abstract (Source: Abdominal Imaging)

Percutaneous cholecystostomy: techniques and applications
AbstractAcute cholecystitis (AC) is a critical condition requiring immediate medical attention and treatment and is one of the most frequently encountered acute abdomen emergencies in surgical practice, requiring hospitalization. Laparoscopic cholecystectomy is considered the favored treatment for patients with AC who are fit for surgery. However, in high-risk patients considered poor surgical candidates, percutaneous cholecystostomy (PC) has been suggested and employed as a safe and reliable alternative option. PC is a minimally invasive, nonsurgical, image-guided intervention that drains and decompresses the gallbladder,...

Segmentation methods applied to MRI-derived radiomic analysis for the prediction of placenta accreta spectrum in patients with placenta previa
ConclusionOur preliminary results show that the VOI including the retroplacental myometrium using T2w images seems to be the best method when segmenting images for the development of ML radiomics predictive models to identify PAS in patients with PP.Graphical abstract (Source: Abdominal Imaging)
