Contrast medium may not be needed at MRI to evaluate all solid tumours but all renal tumours in childhood merit gadolinium-enhanced sequences to assess for contralateral tumour.
Post contrast enhanced MR images are useful too in general, because enhanced sequences are necessary to fully evaluate lymphatic and vascular malformations, both of which can mimic malignant solid masses.
Sanders et al. [ 61] examined 21 patients between 1 and 22 months following osteochondral transplantation using a series of five dynamic contrast-enhanced sequences at 1-min intervals post contrast.
The DCE MRI included acquisition of one pre-enhanced and four enhanced sequences with a time resolution of 85 s.
Motoori et al proposed that the detection of myxomatous tissue on T2W, inversion recovery, DWI, and dynamic contrast-enhanced sequences help to differentiate BMT from other malignant tumours [56].
We had applied these enhanced sequence search strategies to 1961 superfamilies and we find similar trends.
Drug induced myocarditis CMR typically shows high signal on T2-weighted sequences, an increased global enhancement ratio and high signal on delayed enhanced sequences (Fig. 7a and b).
Axial T1- and T2- weighted and gadolinium-chelate enhanced sequences are recommended, preferably with breath-holding technique and on the same (type of) MR system, but no specifications are given.
Yet watching a technologically enhanced sequence in which a first world war soldier playfully juggles a beer bottle, then strums it like a guitar, all I could think was how real, how immediate, how profoundly truthful it all felt.
The GV of each enhanced sequence is increased up to the level where the MCD between the converted sequence and its enhanced version reaches a preset threshold value, denoted as θ MCD.
An external body surface coil (eight channels) was used, with a field of view (FOV) equal to 24 cm, except for the dynamic contrast-enhanced sequences for which FOV was 42 cm.
