Neural Network Ensemble-Based Computer-Aided Diagnosis for Differentiation of Lung Nodules on CT Images

Rationale and Objectives To evaluate the diagnostic performance of a neural network ensemble-based computer-aided diagnosis (CAD) scheme for classifying lung nodules on thin-section computed tomog...

Methemoglobin Suppression in a 0.3 Tesla Magnet

Rationale and Objectives The aim of this study was to design a pulse sequence that suppresses methemoglobin and is applicable in a 0.3-T permanent magnet. Materials and Methods Blood samples wer...

Lung Perfusion with Dual-Energy Multi-detector Row CT

Rationale and Objectives The aim of this study was to evaluate whether the spectral characterization of the iodine content of lung microcirculation could help identify ground-glass opacity (GGO) o...

Low-Dose, Time-Resolved, Contrast-Enhanced 3D MR Angiography in the Assessment of the Abdominal Aorta and Its Major Branches at 3 Tesla

Rationale and Objectives The aims of this study were to evaluate the effectiveness of low-dose, contrast-enhanced (CE), time-resolved, three-dimensional magnetic resonance angiography (MRA) in the...

Is Surgical Excision of Core Biopsy Proven Benign Papillomas of the Breast Necessary?

Rationale and Objectives The aim of this study was to determine if core biopsy–proven benign papillomas of the breast need to be surgically excised. Materials and methods Mammographic and pathol...

Is an ROC-type Response Truly Always Better Than a Binary Response in Observer Performance Studies?

Rationale and Objectives The aim of this study was to assess similarities and differences between methods of performance comparisons under binary (yes or no) and receiver-operating characteristic ...

FDA & Digital Mammography

Digital mammography is routinely used in the US to screen asymptomatic women for breast cancer and currently over 50% of US screening centers employ the technology. In spite of FDAs knowledge that ...

Dual Transfer of GFP Gene and MGd into Stem-Progenitor Cells

Rationale and Objectives The aim of this study was to develop a new technique, the use of magnetic resonance (MR) imaging (MRI) to monitor gene/MR–cotransferred stem-progenitor cells (SPCs) recrui...

Direct Diagnosis in Radiology Cardiac Imaging

Thieme’s entry on cardiac imaging in the Dx-Direct series is very impressive. Many factors (positive, of course) identified while reviewing this book prompted me to remark to myself that there woul...

Decision Analytic Model for Evaluation of Suspected Coronary Disease with Stress Testing and Coronary CT Angiography

Rationale and Objectives The aim of this study was to apply a decision analytic model for the evaluation of coronary artery disease (CAD) to define the optimal utilization of coronary computed tom...
