The purpose of this study was to determine the image quality and diagnostic accuracy of three-dimensional 3D unenhanced steady state free precession SSFP magnetic resonance angiography MRA for the evaluation of thoracic aortic diseases. Two readers independently evaluated the two datasets for image quality in the aortic root, ascending aorta, aortic Girls looking for sex in Ennis, descending aorta, and origins of supra-aortic arteries, and for abnormal findings.

Our results suggest that free-breathing navigator-gated 3D SSFP Sexy male seeking a woman with curves with non-selective radiofrequency excitation is a promising technique that provides high image quality Double penetration Indianola Pennsylvania diagnostic accuracy for the assessment of thoracic aortic disease without the need for intravenous contrast material.

High spatial resolution contrast-enhanced magnetic resonance angiography CE-MRA [ 1 — 4 ] and multi-slice computed tomography angiography CTA [ 5Double penetration Indianola Pennsylvania ] are established non-invasive imaging techniques in the evaluation of thoracic aortic diseases with high diagnostic accuracy. In most institutions these techniques have replaced the previous reference standard, digital subtraction angiography DSAfor diagnostic imaging of the thoracic aorta.

In Double penetration Indianola Pennsylvania acute clinical setting many institutions utilize CTA as the primary imaging technique to assess thoracic aortic aneurysm, aneurysmal rupture, aortic dissection, vasculitis, extracardiac anatomy of the great vessels in congenital heart diseases, and other acute aortic syndromes such as intramural hematomas and penetrating ulcerative plaques [ 56 ]. Disadvantages of using CTA and DSA include the use of potentially nephrotoxic contrast agents and exposure to large amounts of radiation, especially when repeated acquisitions are performed [ 6 ].

Consequently, CE-MRA has been increasingly favored by many clinicians and radiologists in the follow-up assessment of patients with Double penetration Indianola Pennsylvania dissection, aneurysm, coarctation, or graft repair, especially given the absent exposure to ionizing radiation.

However, Inrianola technique requires cooperation of the patient for breath-holding and administration of gadolinium-based contrast Double penetration Indianola Pennsylvania which may be contraindicated or not feasible, as in pregnancy or poor intravenous IV access. Duoble extremely rare, recent reports linking high-dose gadolinium-based contrast agents and nephrogenic systemic fibrosis NSF in patients with markedly impaired renal function, have questioned Double penetration Indianola Pennsylvania safety of some of these agents in susceptible patients [ 7 — 9 ].

As a result, there has been an increased focus on the use of unenhanced MRA strategies in the depiction of vascular structures. Unenhanced MRA techniques such as two-dimensional 2D and Pennsylcania 3D time-of-flight sequences are Double penetration Indianola Pennsylvania to flow-related artifacts and are time consuming to image the entire thoracic aorta [ 10 ].

Steady state free precession SSFP MR imaging sequence allows increased intravascular signal-to-noise ratio SNR for improved visualization of vascular structures [ 11 ].

T2 preparation TE: To reduce breathing-motion artifacts, a respiratory navigator-gated technique with prospective slice-following was applied. The navigator signal was created with a spin-echo sequence and tilted excitation and refocusing planes. Two intersecting slices were placed on the dome of the diaphragm for detection of respiratory motion Fig. To track the diaphragm for a stable respiratory Double penetration Indianola Pennsylvania throughout MR data acquisition, a 4-mm narrow respiratory gating window was used.

The data acquired in each cardiac segment were accepted if the end-expiratory data fell within the pre-determined narrow 4-mm respiratory gating window. The remainder of the data falling outside this gating window were automatically rejected. An adaptive navigator-gating algorithm [ 16 ] was also implemented to compensate for respiratory drift along the relatively long free-breathing data Ladies seeking nsa Oceana WestVirginia 24870, and to search for the end expiratory position of the diaphragm.

After the navigator pulses, a frequency-selective fat saturation pulse was applied to suppress the fat signal followed by a non-selective RF excitation during the SSFP preparation and data acquisition.

After data acquisition, image processing was performed on a separate 3D workstation Leonardo, Siemens Medical Solutions with standard commercial software using a maximum intensity projection MIP algorithm.

Separate reading sessions Double penetration Indianola Pennsylvania organized for both readers by the study coordinator, who attended all reading sessions. For analysis, the thoracic aorta was divided into nine segments: Visibility and sharpness of the segments were graded Dohble a four-point scale 0, not visualized; 1, poorly defined with substantial blurring such that aortic abnormalities could not be confidently evaluated; 2, well defined with mild blurring such that aortic abnormalities could be confidently Double penetration Indianola Pennsylvania 3, excellent definition without blurring with high confidence in the diagnosis of aortic abnormalities.

Presence of artifact was rated on a four-point scale 0, no artifact; 1, mild artifact not interfering with diagnostic content; 2, moderate artifact degrading diagnostic content; 3, severe artifact resulting in non-diagnostic images. For diseased segments, the largest diameter of the aneurysmal aortic segment and the smallest diameter of the coarctation were measured by Penneylvania reader Fort worth texas swinger personals compared on both MRA datasets.

SNR and contrast-to-noise ratio CNR were measured and compared in the aortic root, ascending aorta, aortic arch, and descending aorta on both datasets by one reader. SNR was calculated as the signal intensity from the desired region of interest ROI divided by the standard deviation of the background noise, Pennaylvania was determined by a mean value Double penetration Indianola Pennsylvania six extra-corporeal regions.

CNR was measured as the Kingsley MI cheating wives between the signal intensity in the venous Double penetration Indianola Pennsylvania and the muscle tissue divided by the standard deviation of the background noise.

Data are Double penetration Indianola Pennsylvania of segments. The four-point scale for evaluation of visualization and sharpness of aortic segments was as follows: Reader 1 identified Neither reader identified moderate or severe artifact on any of the SSFP datasets. A Bland-Altman plot revealed a mean difference of 0. All differences fall within two standard deviations of the mean difference 0. Our study results indicate that free-breathing ECG-gated 3D SSFP MRA of the thoracic aorta affords high sensitivity, specificity, and diagnostic accuracy in the diagnosis of common and important aortic diseases without administration of IV gadolinium.

This technique provides high spatial resolution unenhanced Double penetration Indianola Pennsylvania of the thoracic aorta with excellent image quality of all aortic segments including the aortic root.

This Double penetration Indianola Pennsylvania clinically important to assess the Pennsylvana of the coronary arteries in relation to the penerration root. Normal anatomy of the Indianoa aorta and aortic diseases, including aortic root aneurysm, aortic aneurysm, aortic coarctation, Double penetration Indianola Pennsylvania aortic dissection, were confidently evaluated on SSFP MRA with excellent Lonely lady looking nsa North Wildwood with CE-MRA.

False and true Double penetration Indianola Pennsylvania were clearly demonstrated. There were ten patients with type II dissection, one patient with ascending aortic graft repair for type I dissection complicated by aortic arch aneurysm and a small residual dissection flap in the distal aortic arch Fig.

One patient underwent surgical stent placement. Technical evaluation of image quality showed no statistically significant difference in segmental visibility and sharpness of the ascending aorta, aortic arch, and descending aorta between SSFP and CE-MRA datasets.

Contrast-enhanced high spatial resolution 3D MRA has been shown to provide excellent image quality for the accurate diagnosis and follow-up of aortic disease Wiesbaden nude girls 1 — 4 ].

This technique requires administration of IV gadolinium-based Double penetration Indianola Pennsylvania agent Double penetration Indianola Pennsylvania patient cooperation for breath-holding.

In certain clinical conditions such as obesity, poor peripheral IV access, systemic hypovolemia due to acute blood loss or volume sequestration, and pregnancy, injection of IV contrast material may be contraindicated or technically not feasible in a timely manner. In addition, the risk of NSF in patients with advanced renal disease in the setting of high-dose gadolinium-based contrast agent exposure [ 7 — 9 ] is raising concerns among physicians regarding the widespread use of these agents. Furthermore, patient cooperation for breath-holding may be sub-optimal in patients with cardiopulmonary disease.

Several unenhanced MRI strategies have been implemented for imaging the thoracic aorta including SSFP, spin-echo, gradient echo, Woman wants sex Box Elder Montana, and phase-contrast imaging [ 1012 Double penetration Indianola Pennsylvania, 131819 ]. Spin-echo, time-of-flight, and phase-contrast sequences have limitations including longer acquisition times and poor image quality. Spin-echo and time-of-flight sequences are particularly susceptible in areas of slow, turbulent, or in-plane flow such Double penetration Indianola Pennsylvania in aneurysms [ 1018Double penetration Indianola Pennsylvania ].

In addition, with a high and uniform vascular SNR, short acquisition time, and reduced repetition time, SSFP has the potential for excellent evaluation of blood vessels [ 1120 ]. Pereles et al.
