T2-weighted image

T2-weighted image

An MRI term for an image created using longer echo time (TE) and repetition times (TR), whose contrast and brightness are predominately determined by T2 signals.

Capsular wall and internal septae of the lesion are isointense on T1-weighted image and hypointense on T2-weighted image; marginally contrast enhancement seen on fat-saturated contrast enhanced T1-weighted image (c).
(d) Plain sagittal T2-weighted image of the abdomen revealed an oval-shaped mass with homogenous, mildly high intensity inside the right psoas major muscle (white arrow).
The lesion was isointense relative to muscle on the T1-weighted image and hyperin tense on the T2-weighted image with a swirled appearance [Figure 1].
Coronal (a) and sagittal (b) non-saturated proton density- weighted images, and axial T2-weighted image (c) show a multifibrillar structure, isointense to muscle in all sequences, in the expected location of the medial patellofemoral ligament, compatible with a supernumerary medial patellofemoral muscle.
Besides, hyper-intensity signal of C3-T2 level of spinal cord in T2-weighted image, and hypo- to isointense in T1-weighted image also noted [Figure 1].
On the T1-weighted image, the tumour showed homogeneous signal intensity equal to that of muscle; on the T2-weighted image, it had heterogeneous, low signal intensity with crack-like high-intensity lesions (Fig.
The selected images are images where the examination occurs during the relaxation took place, such as T1-weighted image and T2-weighted image (Figure 2).
Crues et al (9) suggests that "It]he knee must be scanned in the axial, coronal and sagittal planes using thin sections (3 to 5 mm thick) with a combination of T1- and T2-weighted techniques, including at least one T2-weighted image with fat suppression." Likewise, Bontrager (10) discusses the value of some of these sequences.
An MRI performed 2 weeks after treatment started indicated enhancement in the lesion on T2-weighted image and fluid-attenuated inversion recovery images had disappeared (Figure, panel D).
Sagittal view of the heterogeneous isointense mass of the T1-weighted image (a), heterogeneous hyperintense mass of the T2-weighted image (b), and enhanced mass of the fat-suppression image by short-T1 inversion recovery (STIR) (c).
Coronal T2-weighted image (b) reveals a round hypointense lesion at the location of interventricular foramen of Monro (arrow in (b)).
The tunica albuginea is seen around the testis as a thin, hypointense rim on both T1 and T2 pulse sequences, better defined on T2-weighted image (Fig.
