Role and usefulness of mr imaging in the assessment of peritoneal carcinomatosis.

Background: For many years, peritoneal carcinomatosis (PC) entitled poor prognosis until the development of the cytoreductive surgery technique associated with hyperthermic intraperitoneal chemotherapy. Imaging of peritoneal carcinomatosis plays an essential role in the diagnosis and management of the patients being considered for cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC).

Main Body: The key role of imaging in patients with peritoneal malignancy is to aid surgical decision making.

Wandering spleen, gastric and pancreatic volvulus and right-sided descending and sigmoid colon.

Wandering spleen is a rare condition, characterized by a mobile spleen that is attached only by an elongated vascular pedicle, allowing it to migrate to any part of the abdomen or pelvis. Mesenteroaxial gastric volvulus usually occurs in children and may be associated with wandering spleen. Both entities result from abnormal laxity or absence of the peritoneal attachments due to abnormal fusion of the peritoneal mesenteries.

Surface primary bone tumors: Systematic approach and differential diagnosis.

Surface primary bone tumors may appear similar to their intramedullary counterpart, but because they are rare, they may pose diagnostic challenges when showing different characteristics compared to their intramedullary counterpart. It is important for radiologists to recognize the imaging findings for various uncommon surface primary bone tumors, which may help to reduce the differential diagnosis or to lead to a specific diagnosis. Radiography is typically used for first-line imaging.

Exercise echocardiography and cardiac magnetic resonance imaging to predict outcome in patients with hypertrophic cardiomyopathy.

Aims: We have observed that wall motion abnormalities (WMAs) during exercise echocardiography (ExE) are associated to events in hypertrophic cardiomyopathy (HCM). Our objective was to evaluate ExE and cardiac magnetic resonance (CMR) to predict outcome in HCM.

Methods And Results: ExE and CMR were performed in 148 patients with HCM.

Atrial abnormalities: spectrum on MRI.

Objective: The purpose of this article is to illustrate the MRI appearance of anatomic variations and congenital heart diseases that involve, directly or indirectly, the atria.

Conclusion: Anatomic variants and congenital diseases involving the atria are characterized by a wide variety of MRI manifestations, most of which can be explained by the underlying pathophysiology and relationship to normal atrial anatomy.
