A vascular intervention followed in 13.9%, while 5.6% of studies led to a contrast-related adverse event. The positive predictive value of a CTA affecting treatment was significantly higher in the presence of high-risk injuries and hard examination findings than in the presence of low...
Multidetector CT (MDCT) can classify both the origin and also the often complex course of anomalous coronary vessels19-22(Figure 4). Magnetic resonance coronary angiography may be an alternative in experienced hands, and the necessity for contrast agent injection and radiation exposure are certainly ...
Typical Clinical Questions and Workflow for a 30-min CMR Exam: Many common questions in cardiovascular practice can be answered with cine, perfusion, and late gadolinium enhancement (LGE) imaging. Myocardial mapping, phase contrast imaging, and other sequences can easily be added to this workflow ...
In contrast resection is warranted for all mucinous cystic neoplasms (MCN) >4 cm and all solid pseudopapillary neoplasms (SPN). Intraductal papillary mucinous neoplasms (IPMN), which are differentiated into main duct (MD-IPMN) and branch duct type (BD-IPMN) IPMN based on the position in the ...
Contrast-enhanced CT of a patient presenting with acute aortic syndrome showing type A-IMH (asterisk) with evolving dissection in the descending aorta. B. Multiplanar reconstruction of the CT in parasagittal orientation delineates small intimal disruption/plaque rupture as the initial site of the ...

Some surgeons consider dense pleural adhesions as a relative contraindication for the VATS lobectomy (15). The authors speculate that pneumolysis can increase the blood loss and obscure the vessels. By contrast, there are experienced surgeons in the field of VATS lobectomies for TB who does not...
The diagnostic results of CT could be further improved via the newly developed techniques of multislice-CT. The highest diagnostic accuracy could be achieved via the use of contrast enhanced MRI with advantageous results for superparamagnetic contrast agents versus hepatobiliary and extracellular...
On modern CMR scanners, virtually all CE-CMRA applications can be performed with a single dose of contrast agent (0.1 mmol/kg). If the area of interest exceeds a single field-of-view (FOV), as is the case for total body or lower extremity artery imaging, a moving table protocol can ...
