PURPOSE: Bronchiolitis obliterans syndrome after lung transplantation (LTx) manifests as a sustained decline in forced expiratory volume in the first second (FEV1). Quantitative computed tomography (QCT) metrics may predict FEV1 better than semiquantitative scores (SQSs), and the transplanted lung may provide better information than the native lung in unilateral LTx. MATERIALS AND METHODS: Paired inspiratory-expiratory CT scans and pulmonary function testing of 178 LTx patients were analyzed retrospectively...

PURPOSE: Graftability of the left anterior descending artery (LAD) has important prognostic value for coronary artery bypass graft (CABG) surgery. However, with a chronic total occlusion (CTO) of the LAD, invasive coronary angiography (ICA) may be insufficient to determine its graftability. We evaluated the role of coronary computed tomographic angiography (CTA) in the assessment of CTO and LAD graftability when the distal vessel segment was incompletely visualized by ICA. MATERIALS AND METHODS: We enrolled 31 patients with equivocal eligibility for CABG due to CTO of the LAD with poor distal flow defined by ICA...

PURPOSE: Cardiac imaging expenditures have come under scrutiny, and a focus on appropriate use criteria (AUC) has arisen to ensure cost-effective resource utilization. Although AUC has been developed by clinical experts, it has not undergone rigorous quality assurance testing to ensure that inappropriate indications for testing yield little clinical benefit. The objective of the study was to evaluate the potential incremental prognostic value of coronary computed tomographic angiography (CCTA) in the different AUC categories...

Cardiac computed tomography angiography (CCTA) is a noninvasive imaging technique that has been rapidly adopted into clinical practice. Over the past decade, technological advances have improved CCTA accuracy, and there is an increasing amount of data supporting its prognostic value in the assessment of coronary artery disease. Recently, "appropriate use criteria" has been used as a tool to minimize inappropriate testing and reduce patient exposure to unnecessary risk and inconclusive studies. This review will summarize the appropriate uses of CCTA in patients before and after cardiac surgery...

Stent placement is commonly used to treat aortic coarctation. Although invasive angiography remains the gold standard, follow-up is often performed using computed tomography, which allows rapid, noninvasive assessment of the aorta and surrounding tissues. The goal of this pictorial essay is to provide a guide to the interpretation of these examinations. Normal and abnormal computed tomographic appearance of different stent types is shown along with reconstructions that can help assess stent integrity and the stent position in relation to the aortic wall and branches...

Chest digital tomosynthesis (DT) has potential advantages compared to computed tomography (CT) such as radiation dose reduction. However, the role of DT in pulmonary nodule management remains investigative. We compared DT against CT for pulmonary nodule detection and size measurement. A clinical population comprising 54 nodules from 30 patients and a screening population comprising 42 nodules from 52 patients were included. Scans were independently read by two radiologists. Agreement in nodule measurements between readers and between modalities was assessed by Bland-Altman analysis using a 95% level of significance...

OBJECTIVE: To evaluate the effectiveness of bone suppression imaging (BSI) software in lung-nodule detection on chest radiographs (CXRs) in relation to nodule location and observer's experience. MATERIALS AND METHODS: The CXRs of 80 patients, of which 40 had a lung nodule (8 to 30 mm in diameter) and 40 did not have any nodules, were interpreted by 20 observers comprising of 7 pulmonologists with >10 years of experience and 13 pulmonology residents. Each patient's image was sequentially read, first using the standard CXR and thereafter with the BSI software...

PURPOSE: Excessive quantity of epicardial adipose tissue (EAT) is considered a risk factor for coronary artery disease (CAD). There are limited data, however, on the relationship between the quality of EAT and CAD. We investigated the association between the density and volume of EAT and subclinical CAD defined by positive coronary artery calcification (CAC), using computed tomography (CT). MATERIALS AND METHODS: We reviewed 609 consecutive CT scans of patients with a mild to moderate risk for CAD to assess the EAT volume, which was measured manually by tracing the parietal pericardial sac on axial images...

PURPOSE: The aim of this study was to assess the left ventricular (LV) remodeling response to chemotherapy in low-cardiac-risk women with newly diagnosed nonmetastatic breast cancer. Cardiotoxic effects of chemotherapy are an increasing concern. To effectively interpret cardiac imaging studies performed for screening purposes in patients undergoing cancer therapy it is necessary to understand the normal changes in structure and function that may occur. METHODS: Twenty women without preexisting cardiovascular disease, of a mean age of 50 years, newly diagnosed with nonmetastatic breast cancer and treated with anthracycline or trastuzumab, were prospectively enrolled and evaluated at four time points (at baseline, during chemotherapy, 2 weeks after chemotherapy, and 6 months after chemotherapy) using cardiac magnetic resonance imaging, blood samples, and a clinical questionnaire...

PURPOSE: The aim was to evaluate computed tomography (CT)-measured pulmonary artery diameter (PAD) and lung density as predictors of pulmonary hypertension (PH) in subjects with systemic sclerosis (SSc). We compared these PAD values with normal values and between SSc subgroups with PH and/or interstitial lung disease (ILD). We investigated whether PAD predicts PH and whether lung densitometry, by using the 85th percentile density value (Perc85) as a measure for ILD, can predict PH. MATERIALS AND METHODS: PAD and Perc85 were measured in axial CT scans and compared between 54 SSc and 76 control subjects...
