Background: Dual-energy CT pulmonary angiography (CTPA) with energy-integrating detector (EID) technology is limited by inability to use high-pitch technique. Objective: To compare image quality of anatomic images and iodine maps between high-pitch PCD CTPA and dual-energy EID CTPA. Methods: This prospective study included 117 patients (median age, 65 years; 70 men, 47 women) who underwent CTPA to evaluate for pulmonary embolism between March 2022 and November of 2022. Fifty-eight patients were randomized to undergo PCD CTPA (pitch, 2...

Breast imaging studies are complex examinations for patients and providers. Breast imaging providers and organizations invest significant resources in educating patients and referring providers to address variability in changing breast cancer screening recommendations, cultural biases, and socioeconomic barriers for patients. The breast imaging examination frequently involves multiple imaging modalities including interventional procedures, thus requiring multiple room types. Practices need to consider variables that affect workflow efficiency throughout the process of scheduling, examination performance, interpretation, and results delivery, as well as options in facilities design to create inviting yet functional environments for patients...

Background: Underlying stroke is often misdiagnosed in patients presenting with dizziness. Although such patients are usually ineligible for acute stroke treatment, accurate diagnosis may still improve outcomes through selection of patients for secondary prevention measures. Objective: To investigate the cost-effectiveness of differing neuroimaging approaches in the evaluation of patients presenting to the emergency department (ED) with dizziness who are not candidates for acute intervention. Methods: A Markov decision-analytic model was constructed from a healthcare system perspective for evaluation of a patient presenting to the ED with dizziness...

Background: CT scanners' net scan state (i.e., image acquisition period) represents a potential target for energy savings through protocol adjustments. However, gauging CT energy savings is difficult without installing costly energy monitors. Objective: To assess correlations between CT dose report metrics and energy consumption during the net scan system state, and to compare theoretic energy savings from matching percentage reductions in energy consumption during net scan and idle system states. Methods: Current sensors were installed on a single CT scanner...

Background: Changes in lung parenchyma elasticity in usual interstitial pneumonia (UIP) may increase the risk for complications after percutaneous transthoracic needle lung biopsy (PTNB). Objective: To investigate the association of UIP findings on CT with complications after PTNB, including pneumothorax, pneumothorax requiring chest tube insertion, and hemoptysis. Methods: This retrospective single-center study included 4187 patients (mean age, 63.8±11.9 years; 2513 men, 1674 women) who underwent PTNB between January 2010 and December 2015...

Background: International medical graduates (IMGs) represent a source of physicians who could help alleviate U.S. radiologist workforce shortages. However, IMGs may face barriers in obtaining appropriate visas (e.g., H1-B or O-1 visas) to allow for faculty employment. Objective: This study aimed to assess the policies and experiences of U.S. academic radiology departments in offering visas to IMGs applying for faculty positions. Methods: A web-based survey on policies and experiences in offering visas to IMG faculty candidates was distributed to chairs of U...

Multiparametric prostate MRI (mpMRI) aids risk stratification of patients with elevated PSA levels. While most clinically significant prostate cancers are detected by mpMRI, insignificant cancers are less evident. Thus, multiple international prostate cancer guidelines now endorse routine use of prostate MRI as a secondary screening test before prostate biopsy. Nonetheless, management of patients with negative mpMRI results (defined as PI-RADS category 1 or 2) remains unclear. This AJR Expert Panel Narrative Review summarizes the available literature on patients with an elevated screening PSA level and a negative prostate mpMRI, and provides guidance for these patients' management...

Background: Adrenal washout CT is not useful for evaluating incidental adrenal masses in patients without known or suspected primary extra-adrenal malignancy. Objectives: To evaluate the diagnostic utility of adrenal mass biopsy (AMB) in patients without known or suspected extra-adrenal primary malignancy. Methods: This retrospective six-center study included 69 patients (mean age 56 years; 32 men, 37 women) without known or suspected extra-adrenal primary malignancy who underwent image-guided core-needle biopsy between January 2004 and June 2021 of a mass suspected to be arising from the adrenal gland...
