Coronary arteries variants & congenital anomalies; using MDCT to assess their prevalence in 1000 of the Egyptian population

Conclusion Wide range of variation was noted among the examined population. Satisfying imaging capability of MDCT was encountered making it an essential tool for assessing coronary artery variants and anomalies before coronary revascularization being accurate & less invasive than conventional angiography.

CT angiography offers excellent anatomic detail necessary for vascular procedural planning including endovascular aneurysm repair (EVAR). However, patients with renal insufficiency are at risk for acute renal failure due to iodinated contrast administration. Catheter-directed CT angiography is a technique in which dilute iodinated contrast is injected into an intra-aortic pigtail catheter during the CT scan. The purpose of this study was to evaluate the safety and efficacy of this technique.

This study compares the effect of Helicobacter (H.) pylori and Lactobacillus (L.) acidophilus on the cytokine profile of PBMCs of 5 men with abdominal aortic aneurysm (AAA) and 5 men with normal/insignificant angiography, CT-Scan and ultrasonography results in the single-culture and in the co-culture with HUVECs. IL-2, IL-4, IL-5, IL-6, IL-9, IL-10, IL-13, IL-17A, IL-17 F, IL-21, IL-22, IFN-γ and TNF-α were measured in culture supernatants using a commercial fluorescent-labeled-bead assay.In general, CagA+ H. pylori-extract induced higher production of IFN-γ, IL-13 and IL-21 by PBMCs. Treatment of ...

This study demonstrates the feasibility of a fully automated technology for the accurate detection and identification of several anatomical reference points (landmarks), commonly used in intravascular imaging. This technology uses two different approaches, specially designed for the detection of aortic root and supra-aortic and visceral branches. In order to adjust the parameters of the developed algorithms, a total of 33 computed tomography scans with different types of pathologies were selected. Furthermore, a total of 30 independently selected computed tomography scans were used to assess their performance. Accuracy was...

Japanese Survey of Radiation Dose Associated With Coronary Computed Tomography Angiography - 2013 Data From a Multicenter Registry in Daily Practice. Circ J. 2020 Feb 18;: Authors: Tanabe Y, Kido T, Kimura F, Kobayashi Y, Matsunaga N, Yoshioka K, Yoshimura N, Mochizuki T Abstract BACKGROUND: Although coronary computed tomography angiography (CTA) is frequently used for identifying coronary artery disease, no studies have investigated the radiation dose in detail in Japan. The aim of this study was to estimate the radiation dose of coronary CTA in Japanese clinical practice and to identify the indepe...

ConclusionThe vessel-specific MCP myocardial perfusion territory assignment technique more accurately quantifies LCA and RCA perfusion territories as compared with the current standard AHA 17-segment model. Therefore, it can potentially provide a more comprehensive and patient-specific evaluation of coronary artery disease.Key Points• The minimum cost path (MCP) technique accurately determines left and right coronary artery perfusion territories, as compared with the American Heart Association 17-segment (AHA) model.• The minimum cost path (MCP) technique could be applied to cardiac computed-tomography angiograph...

Authors: Al-Rudaini HEA, Han P, Liang H Abstract BACKGROUND: CT Angiography (CTA) of aortoiliac and lower extremity arteries is a relatively recent innovation of CT imaging that has changed after the introduction of multi-detector row scanners. OBJECTIVE: The study aimed to evaluate the diagnostic accuracy of Multidetector Computed Tomographic Angiography (MDCTA) in the assessment of arterial tree in patients with Peripheral Arterial Occlusive Disease (PAOD), as compared to Digital Subtraction Angiography (DSA). METHODS: A single-center nonrandomized prospective study was conducted on 50 patients complainin...
