Magnetic resonance imaging is the most important diagnostic method in the investigation of the pituitary lesions. Our aim is to determine whether T2-weighted coronal images may be helpful in the evaluation of the pituitary gland with suspected pituitary adenomas. One hundred and sixty-seven patients were examined prospectively with T2-weighted coronal and T1-weighted coronal images enhanced wit...

Thin (5-mm) coronal high-field (1.5-T) MR images of four human brain specimens and 14 normal volunteers were correlated with myelin-stained microtomic sections of the specimen cerebella. The primary white-matter tracts innervating several hemispheric (posterior quadrangular, superior, and inferior semilunar, gracile, biventer, tonsil) and vermian (declive, folium, tuber) lobules are oriented pe...

OBJECTIVE The purpose of this study was to evaluate the diagnostic efficacy of using additional oblique coronal MRI of the knee for grading anterior cruciate ligament (ACL) graft injury after ligament reconstruction surgery. MATERIALS AND METHODS We retrospectively reviewed 51 consecutive MR knee examinations of 48 patients who underwent both ACL reconstruction and follow-up arthroscopy. The ...

Figure 1. The fat-suppressed T2-weighted coronal image shows a small partial articular surface tear (arrow) evident at the anterior margin of the infraspinatus insertion. Underlying subchondral cystic changes and reactive marrow edema (arrowhead) are seen within the greater tuberosity. A 22-year-old professional baseball pitcher presents with persistent posterior shoulder pain after throwing. A...

background & aim: dbs (deep brain stimulation) is a new and successful technique in treatment of symptoms of parkinsonism especially after drug resistance. research in this field is mostly designed for evolution of this technique. the present study aimed at evaluating the relationship between the angle formed in midsagittal and stn (sub-thalamic nucleus) axis line and recording length in the fi...

BACKGROUND AND PURPOSE XETA, also known as Cube, is a relatively new 3D FSE sequence that can be used to perform whole-brain FLAIR T2-weighted imaging at isotropic high spatial resolution. This high-resolution volumetric imaging, coupled with both fat and fluid suppression, permits ideal evaluation of optic nerve anatomy and signal intensity; therefore, we hypothesized that XETA FLAIR would be ...

BACKGROUND AND PURPOSE Accurate measurement of aortic annulus diameter is crucial for choosing suitable prosthetic size for transcatheter aortic valve implantation (TAVI). Several imaging methods are available for the measurement, but significant variability between different modalities has been observed. The purpose of this study was to systematically compare the measurements of aortic annulus...

Figure 1. Axial MRI T2-weighted (A) and coronal FLAIR (B) sequences reveal a slightly hyperintense, well-defined hypothalamic/third ventricular tumor (arrows), with perilesional vasogenic edema (arrowheads). C: Axial MRI T1-weighted sequence reveals a predominantly isointense tumor (arrow). D: Gadolinium-enhanced sagittal MRI T1-weighted sequence reveals the tumor with uniform contrast enhancem...

Magnetic resonance neurography was used to directly image cervical spinal nerves in patients with clinical and radiographic evidence of cervical radiculopathy. A magnetic resonance imaging phased-array coil system was used to obtain high-resolution coronal T1-weighted spin echo, coronal/axial T2-weighted fast spin echo with fat saturation, and coronal/axial fast short tau inversion recovery wei...

Figure 1: (A) Transaxial T2-weighted image showing a clear structural relationship of the tumour and blood vessels. (B) Coronal T2-weighted image showing the tumour with heterogeneous signal intensity, and predominantly with high signal intensity. (C) Coronal-enhanced T1-weighted image showing a huge tumour: 21.5 × 8.4 × 9.8 cm, encompassing the left common carotid artery, pressing against the ...
