Detecting Epidermal Growth Factor Receptor Tumor Activity In Vivo During Cetuximab Therapy of Murine Gliomas

Rationale and Objectives Noninvasive molecular imaging of glioma tumor receptor activity was assessed with diagnostic in vivo fluorescence monitoring during targeted therapy. The study goals were ...

Comparison of 2D and 3D Views for Evaluation of Flat Lesions in CT Colonography

Rationale and Objectives Flat lesions in the colon may result in false-negative computed tomography colonography interpretations. It is unknown whether flat lesions are better measured on two-dime...

Cerebral Cavernous Hemangiomas at 7 Tesla

Rationale and Objectives Cavernous malformations (cavernomas) occur in 0.4%–0.9% of the population. The most common symptoms of cavernous malformations are seizures. An improved detection of small...

Automatic Identification of the Reference System Based on the Fourth Ventricular Landmarks in T1-weighted MR Images

Rationale and Objectives The reference system based on the fourth ventricular landmarks (including the fastigial point and ventricular floor plane) is used in medical image analysis of the brain s...

Thermal Ablation

Rationale and Objectives To compare thermal dosimetry metrics for specified diameters of coagulation achieved using three different ablation energy sources. Materials and Methods 204 ablations m...

Should Radiology Residents Be Taught Evidence-Based Radiology? An Experiment with “The EBR Journal Club”

Rationale and Objectives Introduce radiology residents to evidence-based radiology (EBR) using a journal club format based on the Radiology Alliance for Health Services Research/American Alliance ...

Radiologist/Educator Knowledge of the Audience Response System and Limitations to Its Use

Rationale and Objectives Audience response systems (ARS) have been proven to increase residents’ retention in the short and long terms. The purpose of this study was to determine what teaching fac...

Peripheral Intravenous Power Injection of Iodinated Contrast Media

Rationale and Objectives Modern computed tomographic scanners and examination protocols often require high injection rates of iodinated contrast media (CM). The purpose of this study was to invest...

Old Dog, New Tricks

This is being written on a new computer and I report, with some trepidation, that I seem to be learning how to use this one. Never mind how long it has taken to pick my way through the new processe...

Multi-voxel Magnetic Resonance Spectroscopy of Cerebral Metabolites in Healthy Adults at 3 Tesla

Rationale and Objectives The objective of this study was to determine how metabolite values (total N-acetyl aspartate [tNAA], glutamate plus glutamine [Glx], total choline [tCho], myoinositol [mI]...
