“…TSE and balanced SSFP, on the other hand were able to independently provide the clinician with this relevant information. When specifically looking at the individual performance of the non-contrast dependent 2D techniques the results we obtained using the TSE sequence are largely in agreement with the study performed by Stemerman et al regarding its ability to obtain the most relevant diagnostic data including wall thickness, thrombus detection, intramural hematoma and signs of emergency [19]. The major draw back of this sequence is the need to use ECG triggering and multiple breath-holds which substantially lengthen the time of the examination thus impeding its application in critically ill patients.…”

“…The most commonly used approach is the FSE sequence that uses double IR pulses with ECG gating (63,64). This involves applying a nonselective IR pulse followed immediately by a section-selective IR pulse, which returns only those spins within the imaging section to their original equilibrium position ( Fig 20) (63). Data are acquired during diastole when the signals from inflowing blood are null after the inversion time.…”

Alongside the two conventional unenhanced magnetic resonance (MR) angiographic techniques, namely time-of-flight and phase-contrast MR angiography, several novel techniques have since been developed, including electrocardiograph (ECG)-gated fast spin echo (FSE), steady-state free precession (SSFP), and arterial spin labeling. These techniques are increasingly being used to avoid severe complications caused by contrast materials, such as iodinated contrast material-induced nephropathy and gadolinium-induced nephrogenic systemic fibrosis. However, image acquisition and interpretation with these techniques are more complicated than with contrast-enhanced MR angiography because of numerous types of artifacts. Appropriate use of these techniques can allow diagnosis of vascular diseases in patients with chronic kidney disease without using contrast materials. For example, time-of-flight angiography is the main technique for evaluating intracranial arteries. Phase-contrast imaging is increasingly being used for physiologic evaluation rather than morphologic evaluation. Meanwhile, ECG-gated FSE MR angiography can show peripheral arteries in more detail. SSFP MR angiography with or without arterial spin labeling can provide high-resolution images of blood vessels including renal arteries, the aorta, and coronary arteries. Black-blood imaging is also used to evaluate vessel walls and intravascular abnormalities including plaque, dissection, and thrombi. The authors review the principles of the currently available unenhanced MR angiographic techniques, along with their advantages and limitations, and describe their clinical applications. This article should help readers select the most appropriate unenhanced MR angiographic technique to assess vascular diseases in patients with chronic kidney disease.

“…As in CA, 3D Gd-MRA does not provide information about the vessel wall. Therefore, black blood MRI using ECG-gated double inversion recovery (DIR) or fast spin echo pulse sequences is essential for the assessment of aortic wall pathologies [43]. DIR acquisition can be obtained with T1-, proton density-or T2-weighted.…”

Intramural hematoma (IMH) is defined as localized hemorrhage within the aortic wall and is included in the acute aortic syndrome spectrum with aortic dissection and penetrating aortic ulcer. The mortality from IMH is similar to classic aortic dissection (21%). 16% of patients with IMH will evolve to classic aortic dissection over time. Despite this confusion exists regarding the precise definitions and radiologic features of IMH versus penetrating ulcers with mural thrombus and overt aortic dissection.
