“…Black-blood MRI sequences, acquired with spin-echo techniques, and often including inversion recovery pulses, are useful for defining morphology across a spectrum of aortic conditions without the need for intravascular contrast medium. [94][95][96][97] With these sequences, the use of multiple radiofrequency pulses nulls the signal from moving blood, causing the dark blood appearance; mobile protons in stable or slowly moving structures (e.g., aortic wall) provide the signal in the image. Aortic wall morphology can be defined and tissue characterized with T1-and T2-weighted sequences and their variants, including T2-weighted dark-blood techniques and T2 turbo spin-echo and short-tau inversion recovery sequences ( Figure 19).…”

“…CMR has been demonstrated to be an excellent diagnostic modality for the thoracic aorta and superior to echocardiography in the evaluation of pulmonary artery size and morphology after surgical repair. 10,11 Though steady-state free precession cine-and phase-contrast velocity mapping are key components of CMR imaging that are routinely used for assessment of semilunar valves and great vessels, reference values for great vessel dimensions by CMR are limited 12 and data pertaining to patients with repaired TOF are unavailable.…”

Background— Cardiac magnetic resonance (CMR) imaging is an important clinical tool for serial follow-up of patients with congenital heart disease, but normative data for great vessel dimensions in pediatric subjects are scarce. We investigated the ascending aortic (AO) and main pulmonary artery dimensions in normal children and young adults in comparison with a cohort of patients with repaired tetralogy of Fallot (TOF). Methods and Results— Subjects were prospectively enrolled for cardiac magnetic resonance after a standardized protocol in 14 participating centers of the German Competence Network for Congenital Heart Defects. All studies were performed in 1.5-T scanners and used single-slice multiphase acquisitions steady-state free precession and velocity-encoded cine. AO and main pulmonary artery areas were measured. The cohort consisted of 483 subjects: 105 normal controls (55 men; 50 women; and median age, 14 years) and 378 patients with repaired TOF (210 men; 168 women; and median age, 16 years). Among TOF, 35 (9%) had pulmonary atresia, 98 (26%) had a palliative procedure before repair, the mean age at repair was 2.9 years, and 82 (23%) used a transannular patch repair. Great vessel areas correlated well with body surface area and age in controls and reference Z-score values were derived. Z scores for ascending AO areas were larger in TOF compared with controls (mean Z score =1.95, P =0.001). In TOF, pulmonary atresia ( P =0.003), male sex ( P =0.01) and previous palliations ( P =0.046) were associated with larger AO areas. Main pulmonary artery area Z scores in surgically modified TOF were smaller on an average than controls (mean Z score =−0.293 P =0.001) but not small to the same extent as the AO was large. Conclusions— This study provides cardiac magnetic resonance reference Z scores for great vessel areas in normal children and adolescents in comparison with a large contemporary cohort of repaired TOF. Male sex, pulmonary atresia, and previous palliations emerged as predictors for larger AO dimensions in TOF. Clinical Trial Registration— URL: http://www.clinicaltrials.gov .

“…In addition MR angiography is a valuable diagnostic instrument for the detection of pulmonary artery stenosis, pulmonary shunting or pulmonary vein stenosis after thoraco-surgical treatment [18]. For complete post-operative evaluation MR angiography should always be combined with unenhanced multiplanar T1w and T2w imaging techniques to detect or exclude perivascular complications such as hematoma or seroma as a possible cause for vascular obstruction [19].…”

CE-MRA in paediatric patients

Contrast enhanced magnetic resonance angiography (CE-MRA) is an established diagnostic method for evaluating vascular disease in adults. However, the use of MRA techniques has spread more slowly in children owing to significant technical challenges in the paediatric population. This article discusses the indications for CE-MRA in paediatric patients, the techniques employed and the imaging findings expected from MRA of children with vascular disease. In particular, the application of "time-resolved" CE-MRA is discussed and clinical case examples are provided to highlight the broad clinical application of this technique in paediatric vascular disease.
