The tremendous variability of the inferior epigastric arterial system makes accurate imaging of the vasculature of the anterior abdominal wall an essential component of optimal perforator selection. Preoperative imaging of the abdominal vasculature allows for preoperative perforator selection, resulting in improved operative efficiency and flap design. Abdominal wall perforators of 1-mm diamete...

Methods Seventy-six prospective patients with known or suspicion of thoracic aortic disease underwent MRA at 1.5T using i) native 3D SSFP MRA with ECG and navigator gating and high isotropic spatial resolution (1.3 × 1.3 × 1.3 mm 3) and ii) conventional contrast-enhanced ECG-gated gradient echo 3D MRA (1.3 × 0.8 × 1.8 mm 3). Datasets were compared at 9 aortic levels regarding image quality (sco...

PURPOSE To evaluate whether renal dimensions and the main renal artery (mRA) diameter can provide indirect evidence of the presence or absence of accessory renal arteries (aRA). MATERIALS AND METHODS The study group consisted of 167 patients (83 women, 84 men; mean age, 52.4±13.1 years) who presented to our radiology department for abdominal CT examinations with various indications. CT examin...

Background Although contrast-enhanced first-pass MRA (FP-MRA) is frequently used to visualize the vasculature, it may not be suitable for the assessment of congenital heart disease. Blood-pool contrast agents remain within the intravascular space for several hours, allowing vessels to be imaged without relying on accurate contrast bolus timing. The purpose of this study is to compare steadystat...

OBJECTIVES The aim was (i) to evaluate the accuracy of equilibrium-phase high spatial resolution (EP) contrast-enhanced magnetic resonance angiography (CE-MRA) at 1.5T using a blood pool contrast agent for the preoperative evaluation of deep inferior epigastric artery perforator branches (DIEP), and (ii) to compare image quality with conventional first-pass CE-MRA. METHODS Twenty-three consec...

BACKGROUND AND PURPOSE We compared 3-dimensional time-of-flight magnetic resonance angiography (3D TOF MRA) using a 3-tesla (T) MR unit with 64-channel multi-detector row computed tomographic angiography (64-MDCTA) for detection and characterization of angiographically proven unruptured intracranial aneurysms. METHODS Thirty-eight patients with 47 aneurysms and 8 patients without aneurysms un...

OBJECTIVE This study compared data on the blood flow velocity in the internal carotid artery, which was obtained using the optical flow method (OFM) with digital subtraction angiography (DSA) and the time-of-flight (TOF) technique using magnetic resonance angiography (MRA). MATERIALS AND METHODS Images were obtained from 12 cerebrovascular patients who underwent both brain DSA and MRA imaging...

BACKGROUND AND PURPOSE Conventional angiography has been historically considered the gold standard for the diagnosis of cervical artery dissection, but MR imaging/MR angiography (MRA) and CT/CT angiography (CTA) are commonly used noninvasive alternatives. The goal of this study was to compare the ability of multidetector CT/CTA and MR imaging/MRA to detect common imaging findings of dissection....
