T2 weighted image

T2 weighted image

image made with a sequence with long TR and TE to show contrast in tissues with varying T2 relaxation times; water gives a strong signal.

Caption: Figure 5: A coronal T2 weighted image shows a high signal intensity cystic lesion (red arrow) within the right main pulmonary artery with multiseptate high intensity cystic lesion on the right hepatic lobe (blue arrow).
(b) Axial T2 weighted image showing the extra axial mass within the suprasellar cistern with internal cysts and solid components that are near isointense to gray matter (Figure 1(b))
(Coronal T2 Weighted Image with Fat Saturation) shows a Stellate Shaped Hyperintense Signal in the Posterior Horn of Medial Meniscus (Arrows) having both Longitudinal and Horizontal Component suggestive of Complex Tear.
A: Heavily T2 weighted image demonstrates left duplicated renal collecting systems (arrowhead) and dilated, tortuous distal ureter on the right (arrow).
The T2 weighted image is highly sensitive for iron oxide particle labelling and its sensitivity can reach 3000 times that of T1 WI or60 times that of T2 WI.
Figure 2: Coronal T2 weighted image demonstrates central pontine involvement with sparing of periphery.
Radiological findings: The signal intensity of the lesion on T1 weighted images may vary from intermediate to high, depending on the protein content or hemorrhage in the cyst, whereas on T2 weighted image, usually found to be high (8).
Imaging findings: Axial T2 weighted image reveals marked hypointensity within bilateral globus pallidus with central hyperintensity.
In study patients, MRI findings suggestive of parametrial invasion included inhomogeneous signal intensity of cervical stroma seen in 42 (32.8%) patients, focal and complete disruption of hypointense cervical stromal ring on T2 weighted images seen in 35 (27.3%) patients, peritumoural fat stranding seen in 30 (23.4%) patients and tumour bulging into parametrial fat or the presence of soft tissue mass/tumour in parametrial tissue seen in 21 (16.4%) patients.
In our case there is iso-intensity on T1 and T2 weighted images and no enhancement, which suggests it may be benign lesion.
It shows typical hypointense rim on both T1 and T2 weighted images representing siderosis.
