Diagnostic Value of Computed Tomography Angiography in Suspected Acute Ischemic Stroke Patients With Respect to National Institutes of Health Stroke Scale Score.

Objective: Noncontrast computed tomography (NCCT) plus computed tomography angiography (CTA) is the standard imaging modality for acute stroke. We investigated whether there is an additional diagnostic value of supra-aortic CTA in relation to National Institutes of Health Stroke Scale (NIHSS) and resultant effective radiation dose.

Methods: In this observational study, 788 patients with suspected acute stroke were included and divided into 3 NIHSS groups: group 1, NIHSS 0-2; group 2, NIHSS 3-5; and group 3, NIHSS ≥ 6.

Breast Abscesses: Diagnosis, Treatment and Outcome.

BACKGROUND: The aim of our study was to analyze diagnostic results, different treatment modalities, and the outcome of patients with breast abscesses treated at our institution in a multi-modality breast team, to determine whether minimally invasive treatments are successful. METHODS: 110 patients with mastitis and suspected breast abscesses at our institution between January 2000 and end of September 2007 were retrospectively analyzed. Abscesses were diagnosed using ultrasonography (US), and the material obtained using US-guided fine needle aspiration (FNA) was further examined.

Massive bleeding of ruptured metastatic hepatic melanoma treated by transarterial embolization.

Although melanoma frequently metastasizes to the liver, its spontaneous rupture is rare. We report herein an unusual case of a 73-year-old man with rupture of multiple hepatic metastases from scalp melanoma and resulting massive intraperitoneal bleeding, which was successfully controlled by transarterial embolization.

Prospective respiratory-triggered multidetector row CT (MDCT) for abdominal examinations: initial experience with a prototype.

Purpose: To develop a prototype for prospective respiratory-triggered multidetector row computed tomography (MDCT) for abdominal examinations and to assess its feasibility.

Materials And Methods: The prototype consisted of the following components: an MDCT unit, personal computer (PC), and a respiratory motion detector in the form of a wearable belt with sensors to measure differences in pressure caused by breathing excursions. The registered signals were processed by the PC.

Endovascular therapeutic options for isolated iliac aneurysms with a working classification.

The purpose of this paper is to demonstrate a variety of stent-grafting and embolization techniques and describe a new classification for endovascular treatment of isolated iliac artery aneurysms. A total of 19 patients were treated for isolated iliac aneurysms. Depending on the proximal iliac neck and the uni-/bilaterality of common iliac artery aneurysms (CIAA's) the patient may be treated by a tube (Type Ia) or a bifurcated stent-graft (Type Ib) in addition to internal iliac artery embolization.
