T1-weighted images generated from (b) spin echo (SE), (c) gradient echo (GRE), (d) spoiled gradient echo (SP-GRE), (e)
inversion recovery spin echo (IR-SE), and (f)
inversion recovery gradient-echo (IR-GRE).
(b) Axial fluid attenuation
inversion recovery (FLAIR) image shows new hyperintense lesions in the bilateral parietooccipital white matter.
(c) T2-weighted spectral attenuated
inversion recovery (SPAIR) image in the sagittal plane showing the cyst formation and surrounding bone marrow edema in the talus underneath the depressed lateral talar dome.
An appropriate inversion time of fast fluid attenuated
inversion recovery made it significant to measure contrast between tissues where signal intensity difference was the smallest and ordinary.

inversion recovery images after contrast injection revealing mild mid-wall enhancement in the basal inferior and inferolateral walls consistent with myocarditis (arrow).
(a) Axial double
inversion recovery sequence through the upper chest demonstrates mural thickening of the brachiocephalic, left common carotid, and left subclavian arteries.
Indeed, four weeks into her hospital stay, a repeat MRI showed new cortical T2 fluid attenuation
inversion recovery (FLAIR) hyperintensities, a repeat 24-hour EEG showed triphasic waves, and neuron specific enolase (NSE) levels, which had not been measured previously, were markedly elevated.
Cranial magnetic resonance imaging (MRI) showed a multiloculated lesion 50 mm x 40 mm in size, hypointense on T1 and hyperintense on both T2 and fluid-attenuated
inversion recovery (FLAIR) images at the left parieto-occipital region with peripheral edema.
Pelvis magnetic resonance imaging documented that both sciatic nerves were increased in intensity in the axial and coronal short-tau
inversion recovery sequences (Figure 1a and b).
MR: axial fluid attenuated
inversion recovery (FLAIR) (A), sagittal FLAIR (B), axial T1 (C), and axial T2 (D) images showing large globular lesions in the deep white matter consistent with demyelinating processes seen in ADEM.
[4] More significantly, as mycetoma is characterised by the formation of 'grains' that are found within abscesses surrounded by abundant granulation tissue, a characteristic appearance is seen on T2-weighted, short tau
inversion recovery (STIR) and T1-weighted fat-saturated post-gadolinium MRI (Fig.
Focal areas of fat within the lesion may be high signal on T1 and
inversion recovery sequences.
