The Superior Thyroid Artery (STA) is the dominant arterial supply of the thyroid gland, larynx and the neck. Awareness of variations in STA is crucial for invasive operations in the neck region. We reported a case that STA derives from the Common Carotid Artery (CCA). A patient with possible transient ischemic attack had an digital substraction angiography. Angiography revealed superior thyroid...

Magnetic resonance angiography (MRA) or magnetic resonance venography (MRV) can be used as a first line investigation of intracranial vascular disease. It is an alternative to invasive intra-catheter angiography that was once the mainstay for the investigation of intracranial vascular disease. MRA/MRV may use a contrast agent, gadolinium, which is non-iodine-based, for better visualization. It ...

Coronary artery disease (CAD) remains one of the leading causes of morbidity and mortality in western society. Over recent decades, major advances have been made in non invasive imaging techniques, resulting in an enormous growth in their role in the clinical assessment of patients with known and suspected CAD. Indeed, although invasive coronary angiography remains the current gold standard in ...

Puerperal hematoma is one of the life threatening obstetrical emergencies. Surgical ligation of bleeding vessel may not always be possible for the patients who were hemodynamically unstable, hence pelvic arterial angiography may be preferred as the first line treatment modality for these cases. Pelvic arterial angiography and embolization is a safe, tolerable, and minimally invasive treatment m...

omputed tomography for coronary angiography (CTCA) as rapidly evolved into a valuable alternative to invasive oronary angiography for accurate noninvasive assessment f coronary morphology. Although increasing values of ositive predictive values are continuously reported, it is enerally accepted that the strength of this technology at resent lies in its excellent ability to exclude coronary arte...

modalities for the evaluation of arterial vessels have been introduced. These include Color Doppler Ultrasound (CDU), spiral Computed Tomography (CT) and Magnetic Resonance [1-5]. The non-invasive character of these techniques represents a major advantage when compared with intra-arterial Digital Subtraction Angiography (DSA). These techniques are redefining the goals of DSA or “catheter based”...

We present three patients who were admitted to our institution with vertebrobasilar dolichoectasia diagnosed at CT angiography. Two patients had associated intraarterial thrombi and one patient had basilar artery dissection. Shaded surface display images were useful in showing arterial anatomy relative to the skull base. Source images and curved-reformatted images were helpful in diagnosing thr...

We report the hemodynamic assessment in a patient with cerebral arteriovenous malformation using time-resolved magnetic resonance angiography (TRMRA), a non-invasive modality, and catheter-based digital subtraction angiography (DSA), before and after embolization. Comparison of the results showed that TR-MRA produced very fast dynamic images and the findings closely matched those obtained at DS...

Assessment of the left internal mammary artery (LIMA) graft patency currently requires invasive investigation through coronary angiography. In the last years the successful application of noninvasive Doppler spectrum analysis has been reported for patency assessment of the LIMA graft after myocardial revascularization. Echocardiography is considered to be a sensitive noninvasive screening modal...

Based on review of available data, the Company may consider the use of noninvasive fractional flow reserve (FFR) following a positive coronary computed tomography angiography (CCTA) to guide decisions about the use of invasive coronary angiography (ICA) in patients with stable chest pain at intermediate risk of coronary artery disease (CAD i.e., suspected or presumed stable ischemic heart disea...
