Aim: The aim of the study is to evaluate the quality of the temporal mandibular joint (TMJ) imaging in patients with lack of condyle-disk coordination with the Half-Fourier Acquisition Single Shot Turbo Spin Echo (HASTE), and compare it with the quality of TSE T2-weighted images.
Methods: Twenty-seven patients were selected (12 men and 15 women; age range 17-69 years) with medical history negative for facial trauma or surgery. The instrument used was a Siemens 1.5 Tesla with bilateral coil dedicated for studying both TMJs. TSE T2-weighted and HASTE images in the parasagittal axis with open and closed mouth were obtained for both joints.
Results: The quality of the TSE T2-weighted images was better for all parameters considered (both at open and at closed mouth) than the HASTE images; however, the latter method is considerably quicker.
Conclusions: HASTE was found to be a valid method for use as rapid screening to study the TMJ and for use in patients who are unable to maintain an immobile position. Time and cost required for the examination are drastically reduced.

Objectives: To investigate the impact of compressed sensing - sensitivity encoding (CS-SENSE) acceleration factor on the diagnostic performance of magnetic resonance imaging (MRI) within standard female pelvis protocol in patients with endometrial cancer.
Methods: T2-weighted turbo spin echo (TSE) sequence from standard female pelvic MRI protocol was chosen due to its long acquisition time and essential role in the evaluation of morphological characteristics of the female pelvic anatomical structures. Fully sampled reference scans and multiple prospectively 2x to 5x under-sampled CS-SENSE scans were acquired.

Purpose: In resective epilepsy surgery for drug-resistant focal epilepsy (DRE), good seizure outcome is strongly associated with visualization of an epileptogenic lesion on MRI. Standard clinical MRI (≤ 3 Tesla (T)) may fail to detect subtle lesions. 7T MRI enhances detection and delineation, the potential benefits of increasing field strength to 9.

Purpose: This study compares the diagnostic efficacy of non-contrast abbreviated MRI protocols with Gadoxetic acid-enhanced abbreviated MRI for detecting colorectal liver metastasis (CRLM), focusing on lesion characterization and surveillance.
Methods: Ninety-four patients, including 55 with pathologically verified CRLM, were enrolled, totaling 422 lesions (287 metastatic, 135 benign). Two independent readers assessed three MRI protocols per patient: Protocol 1 included non-contrast sequences (T2-weighted turbo spin-echo, T1-weighted Dixon, diffusion-weighted imaging (DWI), and ADC mapping).

Objectives: Nonenhanced T1-w sequences such as magnetization-prepared 2 rapid acquisition gradient echo (MP2RAGE) and derived fluid and white matter suppression (FLAWS) have demonstrated high performance for detecting brain parenchymal and cervical spine demyelinating lesions in multiple sclerosis. However, their potential for identifying optic nerve (ON) demyelination remains unexplored. The aim of this study was to evaluate the performance of compressed sensing-accelerated (CS) MP2RAGE-FLAWS imaging for detection of ON demyelination lesions compared with T2-w fat-saturated (FS) TSE imaging in a clinical setting.
