Multi-phase coronary magnetic resonance angiography improves delineation of coronary arteries.

CONCLUSION: The 3D multi-phase CMRA approach allows a time efficient depiction of the coronary arteries and a coeval functional assessment, with an improved vessel sharpness of the coronaries. PMID: 30799635 [PubMed - as supplied by publisher]

This patient was working on his truck in a garage without ventilation and the vehicle was running. He felt dizzy and lost consciousness. The next thing he remembers is waking up in the ambulance. He was last seen normal at 09:00 AM and was found down at 10:30 AM. He denied chest pain, abdominal pain, SOB or any other symptoms, though he did endorse chest pressure when asked specifically.He underwent a routine ECG prior to hyperbaric therapy for CO poisoning:Obvious Massive STEMI, Proximal LAD OcclusionHis CO level returned at 34%.Further h/o revealed that he had had a proximal LAD stent placed for a Non-Occlusion MI more t...

Authors: Xu J, Wang X, Xiao H, Xu J Abstract BACKGROUND To determine the difference in size-specific dose estimates (SSDEs), separately based on effective diameter (deff) and water equivalent diameter (dw) of the central slice of the scan range in computed tomography coronary angiography (CTCA). MATERIAL AND METHODS There were 134 patients who underwent CTCA examination, were electronically retrieved. SSDEs (SSDEdeff and SSDEdw) were calculated using 2 approaches: deff and dw. The median SSDEs and mean absolute relative difference of SSDEs were calculated. Linear regression model was used to assess the absolute rel...

Conclusion: In this study, we found that stent-assisted coil embolization with NeuroForm Atlas stent may be safe and effective in the treatment of wide-neck intracranial aneurysms. NeuroForm Atlas SAC is feasible for the treatment of both ruptured and unruptured wide-neck aneurysms. PMID: 31805757 [PubMed - as supplied by publisher]

ConclusionThe incidence of artery-to-urinary tract fistulas is growing due to the increasing use of urologic and vascular surgery, pelvic oncologic surgery, and radiation therapy. In addition to fistulas involving a degenerated artery and ureter or synthetic grafts and ureter, they can also involve an autogenous vein graft and the urinary bladder. In our patient, the fistula was a result of erosion of the bladder from a pseudoaneurysm at the proximal anastomosis of an autogenous vein iliofemoral bypass in an extra-anatomic position. Open surgery remains the best treatment option, although there is increasing evidence of su...

A 64-year-old woman with a history of cirrhosis and progressive difficulty breathing underwent pulmonary ventilation/perfusion SPECT to evaluate possible pulmonary embolism. The images demonstrated multiple mismatched ventilation/perfusion defects in both lungs, suggesting pulmonary embolism. However, there was also 99mTc-MAA radioactivity in the brain and bilateral kidney, with a right-to-left shunting rate of 8.8%. In addition, CT pulmonary angiography did not demonstrate embolus. The findings indicated that perfusion defects were caused by hepatopulmonary syndrome.

Objective The aim of this study was to compare the risk of hypersensitivity reactions to iopromide after intra-arterial (IA) administration and intravenous (IV) administration. Materials and Methods Four observational studies were pooled. Almost half of the study population (48.1%) was from Europe, and one quarter each from China (27.6%) and other Asia countries (24.1%). All patients received iopromide either intra-arterially or intravenously for angiographic procedures (mostly cardio-angiography) or contrast-enhanced computed tomography. A nested case-control analysis, including a multivariable logistic regression mo...

Objectives The aim of this study was to compare image quality, conspicuity, and endoleak detection between single-energy low-kV images (SEIs) and dual-energy low-keV virtual monoenergetic images (VMIs+) in computed tomography angiography of the aorta after endovascular repair. Materials and Methods An abdominal aortic aneurysm phantom simulating 36 endoleaks (2 densities; diameters: 2, 4, and 6 mm) in a medium- and large-sized patient was used. Each size was scanned using single-energy at 80 kVp (A) and 100 kVp (B), and dual-energy at 80/Sn150kVp for the medium (C) and 90/Sn150kVp for the large size (D). VMIs+ at 40 k...
