Purpose:
Existing diagnostic radiology peer-review systems do not address the specificities of interventional radiology (IR) practice. The purpose of this study was to assess the feasibility of a specifically developed interventional peer review method, IR Peer.
Materials And Methods:
Retrospective review of a prospectively encoded pilot database aimed at demonstrating the feasibility of IR Peer in a multiphysician practice was performed. This scoring system used morning peer review of selected IR cases from the previous day in the form of a five-item questionnaire and an ordinal answer scale that grades reviewers' agreement with imaging findings, procedural/technical management, early outcomes, and follow-up plan. Patient lists from IR Peer and morbidity and mortality (M&M) conferences were compared to evaluate the amount of overlap and capability of IR Peer to help detect adverse events (AEs).
Results:
A total of 417 consecutive reviews of IR attending physician cases by peers were performed in 163 consecutive patients over 18 months, and 94% of cases were reviewed by two or three IR attending physicians. Each question was answered 99%-100% of the time. Answers showed disagreement in 10% of cases (2% by a single reviewer, 8% by several), most related to procedural technique. Overall AE incidence was 1.8%. IR Peer contributed 10.7% of cases to the M&M list.
Conclusions:
IR Peer is feasible, relevant, and easy to implement in a multiphysician IR practice. When used along with other quality-assurance processes, it might help in the detection of AEs for M&M; the latter will require further confirmatory research.

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
