To report our experience with MRI in the preoperative evaluation of patients with traumatic penile fractures. ⋯ Many imaging methods are available to evaluate traumatic penile lesions: ultrasound, colour-Doppler ultrasound, urethrography, cavernosography, angiography and MRI. In agreement with the literature, our experience shows that MRI is useful in evaluating penile injuries owing to its multiplanar capabilities, its good spatial resolution and its excellent tissue contrast resolution. These characteristics enabled a more adequate surgical approach. In our view, MRI can be regarded as an emerging method to obtain helpful diagnostic information, with no risks for the patient.

[Focal liver lesions: characterization with quantitative analysis of T2 relaxation time in TSE sequence with double echo time].
To evaluate the accuracy of calculation of T2 relaxation time with simplified algorithm in characterization of liver focal lesions with Turbo Spin Echo (TSE) T2-weighted sequences with double echo time (TE). ⋯ Introducing double echo time TSE sequences in the protocol of liver study concurs to obtain high diagnostic accuracy in the characterization of the hepatic lesions. The quantitative analysis of T2 represents a useful additional instrument to the morphologic analysis in discrimination between hepatic lesions and can be carried out by TSE sequences with elevated reliability reducing the imaging time compared with conventional sequences. The evaluation of hepatic lesions of less than one centimeter should always include analysis of dynamic gadolinium-contrast images.
