Anatomical Evaluation of the Dural Sinuses in the Region of the Torcular Herophili Using Three Dimensional CT Venography

Rationale and Objectives The torcular herophili, or “confluence of the sinuses,” shows various configurations with other venous sinuses, as revealed by angiography. The aims of this study were to ...

Acute Mesenteric Ischemia Induced by Ligation of Porcine Superior Mesenteric Vein

Rationale and Objectives To evaluate multidetector computed tomography (MDCT) for detecting the early changes and dynamic evolution of acute mesenteric ischemia (AMI) induced by the ligation of su...

14-Mile Hike

When I was a Boy Scout and working on my ranks, one of my obligations was to take a 14-mile hike. I had known about this since I was a Cub Scout and had thought about it, talked about it, and made ...

The Effect of Two Priors on Bayesian Estimation of “Proper” Binormal ROC Curves from Common and Degenerate Datasets

Rationale and Objectives We showed previously that maximum-likelihood (ML) and Bayesian (with a flat prior on a common parameterization of the model) estimates of “proper” binormal receiver operat...

The Degree of Stenosis on Cardiac Catheterization Compared to Calcified Coronary Segments on Multi-Detector Row Cardiac Computed Tomography MDCT

Rationale and Objectives Cardiac computed tomography is increasingly being used to assess the degree of stenosis in coronary arteries. It has been shown in multiple studies to have high negative p...

Second Homes

In another Chronicle, I took up details about having a home, which was difficult to finance and demanding for upkeep and maintenance. Nothing spectacular, but a substantial investment of time and e...

Radioablation Settings Affecting the Size of Lesions Created Ex Vivo in Porcine Livers with Monopolar Perfusion Electrodes

Rationale and Objectives To explore the morphological characteristics of ablated lesions and find which combination of duration, temperature, and power was preferable to create largest lesion size...

Perceptions of Lung Cancer Risk and Beliefs in Screening Accuracy of Spiral Computed Tomography among High-Risk Lung Cancer Family Members

Rationale and Objectives Spiral computed tomography (SCT) is being evaluated as a screening tool for lung cancer. Our objective was to describe the effect of participation in SCT screening on part...

On the Convexity of ROC Curves Estimated from Radiological Test Results

Rationale and Objectives Although an ideal observer’s receiver operating characteristic (ROC) curve must be convex—ie, its slope must decrease monotonically—published fits to empirical data often ...

Nanoscaled Iodized Oil Emulsion as a CT Contrast Agent for the Detection of Experimental Liver Tumors in a Rat Model

Rationale and Objectives To characterize an iodized oil emulsion for computed tomography (CT) imaging of experimental hepatic tumors in rat models. Materials and Methods For characterizing the a...
