Patients with rectal cancer have a dilated IMV compared with patients without rectal cancer. We confirm that IMV diameter is a potential surrogate marker of LN status and EMVI at baseline. IMV diameter is also a marker of tumour, LN and EMVI response to chemoradiotherapy.
Radiology misses have been the subject of much debate on both sides of the Atlantic in recent years. There is now greater focus in trying to reduce radiology errors by continuous education and changing the working environment to try and protect the radiologist, and ultimately the patient from potential harm. Duty of candour is a relevant and sensitive area. Developing robust validated reporting pathways within the healthcare structure is very important so as to encourage a "learning from discrepancies" culture and to put the patient and their families at the center of reporting and acknowledging errors in radiology. Having reflected in our daily practice and while writing this pictorial review, we have concluded that during reporting MRI scans, routine assessment of the localizer images, focusing outside the area of interest and having a more structured approach to image interrogation are key actions which may help reduce the number of omissions. We present a myriad of cases where pathology was "missed" outside the center of gaze in relation to the abdomen or outside the abdomen on abdominal MRI, and suggest key high yield sequence related review areas to minimize the chance of missing potentially significant pathology.
The process of abnormal reparative or reactive processes in the abdominal cavity, can lead to sclerosis and fibrous deposition. The relatively recent discovery of an IgG4 subgroup of immune mediated sclerosing disease 1,2 has thrown some light on the pathophysiology of these conditions. Firstly, our pictorial review aims to describe imaging findings to enhance the general radiologist's recognition and interpretation of this varied group of benign sclerotic and fibrotic abdominal processes. Secondly, along with the imaging findings, we bring into discussion the potential mimics of these pathologic processes to minimise interpretational errors. Moreover, some of the mimics of these processes are in the spectrum of malignant disease. Most importantly, to ensure a correct diagnosis thorough clinical and histopathological assessment are required to support the imaging findings presented in this review.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
