Incidence of malignancy in lung lesions initially classified as organizing pneumonia on CT-guided biopsies.

Purpose: Organizing pneumonia is an inflammatory disorder that may co-exist with malignancy in the lung or elsewhere in the body. We aimed to assess patients with a lung biopsy diagnosis of organizing pneumonia for subsequent pathology confirmation of co-existing malignancy.

Methods: In this retrospective IRB-approved, HIPAA-compliant study, 1314 consecutive patients who underwent CT-guided lung biopsy for suspected lung cancer or metastatic disease from 02/2014 to 04/2022 at a single tertiary referral hospital were identified.

Adjusting Atrial Size Parameters for Body Surface Area: Does it Affect the Association With Pulmonary Embolism-related Adverse Events?

Purpose: Small left atrial (LA) volume was recently reported to be one of the best predictors of acute pulmonary embolism (PE)-related adverse events (AE). There is currently no data available regarding the impact that body surface area (BSA)-indexing of atrial measurements has on the association with PE-related adverse events. Our aim is to assess the impact of indexing atrial measurements to BSA on the association between computed tomography (CT) atrial measurements and AE.

New Imaging Protocol to Assess Endotracheal Tube Placement: A Case-control Study.

Purpose: After intubation, a frontal chest radiograph (CXR) is obtained to assess the endotracheal tube (ETT) position by measuring the ETT tip-to-carina distance. ETT tip location changes with neck position and can be determined by assessing the position of the mandible. As the mandible is typically not visualized on standard CXRs, we developed a new protocol where the mandible is seen on the CXR, hypothesizing that it will improve the accuracy of the ETT position assessment.

Approach to Imaging Ischemia in Women.

Approach to imaging ischemia in women Coronary artery disease in women tends to have a worse short- and long-term prognosis relative to men and remains the leading cause of mortality worldwide. Both clinical symptoms and diagnostic approach remain challenging in women due to lesser likelihood of women presenting with classic anginal symptoms on one hand and underperformance of conventional exercise treadmill testing in women on the other. Moreover, a higher proportion of women with signs and symptoms suggestive of ischemia are more likely to have nonobstructive coronary artery disease (CAD) that requires additional imaging and therapeutic considerations.
