Comparative Study
Comparison of extracolonic findings and clinical outcomes in a screening and diagnostic CT colonography population.
To compare the distribution of extracolonic findings and clinical outcomes between screening and diagnostic CT colonography (CTC) populations. ⋯ The distribution of extracolonic findings and clinical outcomes were not statistically significantly different between screening and diagnostic CTC populations.
-
To compare the rates of colorectal and extracolonic findings at CT colonography (CTC) screening between patients with and without a personal prior history of other. ⋯ Relevant colorectal and extracolonic findings at CTC screening are increased in patients with a previous extracolonic cancer history, particularly among certain cancer subsets. These results may have important implications for choice of colorectal test in these patients.
-
To evaluate precision of a software-based liver surface nodularity (LSN) score derived from CT images. ⋯ The software-based LSN score is a quantitative CT imaging biomarker with excellent repeatability, reproducibility, inter-observer agreement, and test-retest repeatability.
-
To evaluate the accuracy of magnetic resonance imaging (MRI) in the diagnosis of acute appendicitis in pregnant patients and the value of additional diffusion-weighted MRI (DWI). ⋯ MRI has high accuracy for the diagnosis of acute appendicitis in pregnant patients. Therefore, MRI is recommended for use as a first-line diagnostic test for pregnant patients with clinically suspected appendicitis.

The aim of the study was to assess the effectiveness of Superb Micro-vascular Imaging (SMI) as an alternative to Contrast-Enhanced Ultrasound (CEUS) and Computed Tomography Angiography (CTA) for endoleak detection and classification in patients followed up after endovascular abdominal aortic aneurysm repair (EVAR). ⋯ The analysis showed that SMI is effective, repeatable, and comparable with the CEUS modality in identification endoleaks after EVAR; it may be considered as a potential tool to monitor patients after EVAR implantation, especially those with renal insufficiency or with an allergy to any contrast media.
