The advent of renal transplantation has significantly improved the quality of life and mortality of patients with end-stage renal disease. Unfortunately, transplant-associated complications (TACs) are common and pose a significant risk to both the allograft and the patient. A major advancement in the care of transplant recipients is the implementation of renal ultrasound, which allows for a more detailed assessment of the renal allograft and facilitates the distinction of different TAC manifestations such as perinephric fluid collections, vascular disease, and parenchymal disease. A better understanding of the clinical and sonographic features of TACs will help guide TAC management and promote better outcomes for renal transplant recipients.

Primary diseases involving the mesentery and omentum are rare and thus easily overlooked. Due to their proximity to the abdominal and pelvic organs, the mesentery and omentum are often victims of inflammation, edema, hemorrhage, and neoplasms. Furthermore, these diseases often have nonspecific and overlapping imaging features, posing a diagnostic challenge to radiologists and necessitating reliance on clinical information. The terms “peritoneum,” “mesentery,” and “omentum” are often used interchangeably, although these structures are not the same. Effective treatment relies on both diagnostic and anatomical accuracy. The goal of this article is to define the peritoneum and its specialized folds and then review a gamut of diseases involving the mesentery and omentum.

MRI is the method of choice for the evaluation of endometrial carcinomas (ECs), from detection to evaluation of recurrent disease. Although the staging of ECs is done surgically using the system of the International Federation of Gynecology and Obstetrics (FIGO), preoperative assessment based on MRI findings helps in risk stratification and decision-making. The main parameters evaluated include the degree and depth of myometrial invasion, parametrial extent, and cervical stromal infiltration. The combination of T2-weighted imaging, dynamic contrast-enhanced MRI, and diffusion-weighted imaging increases the accuracy of EC diagnosis and staging. A proposed step-by-step guide was developed to help the radiologist formulate hypotheses and guide clinical reasoning from the approach of the patient to the preparation of the final report. A structured report is also proposed with the objective of improving report quality and facilitating communication with the treating physicians.

Contrast-enhanced mammography (CEM) is a new breast imaging technique. CEM provides morphologic (mammography) and functional information obtained after the injection of iodinated contrast material. We review the basics and state-of-the-art CEM, highlighting the potential challenges to implement CEM in a breast imaging department. We also provide an update in CEM technique and interpretation; the performance of this modality versus conventional breast imaging modalities (mammography, ultrasound, and MRI); existing clinical applications; potential challenges; and pitfalls.

Chronic liver disease is the 11th leading cause of mortality in the United States.1 Portal hypertension is a common endpoint for progressive liver disease, and can clinically manifest as refractory ascites, splenomegaly, and life-threatening esophageal and gastric variceal bleeding. Transjugular intrahepatic portosystemic shunt (TIPS) is an endovascular procedure that treats portal hypertension by making a connection between the portal and systemic venous systems. By creating a low-resistance outflow tract for portal venous drainage, TIPS decreases portal hypertension and its dangerous sequelae in patients not responding to medical therapy.

Hand and finger imaging is routine, usually due to traumatic and degenerative conditions. Many common and uncommon soft-tissue tumors also occur in the hand, and the diagnosis can raise doubts and confuse radiologists and other specialties. This presentation aims to present soft-tissue tumors and bone tumors of the hand, review the various imaging features of these tumors, and discuss how the imaging features can help provide a differential diagnosis. Of the totality of tumors that arise in the hands and fingers, the vast majorities are benign, and radiologists' familiarity with the appearance of these masses on imaging can help with the clinical outcome.

Esophageal perforation and anastomotic leak of the postsurgical esophagus place patients at significant risk for morbidity and mortality, requiring prompt and accurate diagnosis through imaging. Plain radiographs may be obtained during the initial evaluation of symptoms but have low sensitivity and specificity for esophageal perforation. With clinical suspicion for perforation, CT with oral contrast should be obtained initially due to its high sensitivity, utility in surgical planning, and usefulness in evaluating underlying causes or other etiologies for symptoms. With a negative CT, perforation is ruled out and subsequent fluoroscopic esophagography is unnecessary. In patients with postsurgical anatomy such as esophagectomy, diagnosis is difficult and concurrent review of CT and fluoroscopy is more sensitive than either modality alone.
