Testicular Ectopia

Transverse testicular ectopia (TTE) is an extremely rare congenital anomaly of the testis, characterized by migration of one testis toward the contrary hemiscrotum. TTE is usually associated with other testicular abnormalities such as persistent Mullerian duct syndrome, hypospadias, true hermaphroditism, and scrotal anomalies. Testicular sonography is the main initial diagnostic modality, followed by magnetic resonance imaging of the scrotum. These imaging modalities are important for determination of TTE and characterization of the testicular lesions. This case report provides the high-resolution ultrasonography, Doppler ultrasonography, magnetic resonance imaging, and diffusion-weighted imaging findings of a young man with seminoma in the transverse testicular ectopia. In addition, data on tumor stiffness, obtained with point shear-wave sonoelastography, are presented.

Successful treatment of posterior tibial tendon dysfunction depends on accurate staging and the appropriate selection of surgical procedures. Magnetic resonance imaging is the most sensitive diagnostic modality for evaluating the tendon and is also the best predictor of clinical outcome following surgery. Procedural selection for patients with posterior tibial tendon dysfunction depends on many factors, including the underlying cause, age, weight, apex of the deformity, and relative integrity of the posterior tibial tendon.

Abstract In the recent years, with the development of ultrafast sequences, magnetic resonance imaging (MRI) has been established as a valuable diagnostic modality in body imaging. Because of improvements in speed and image quality, MRI is now ready for routine clinical use also in the study of pulmonary diseases. The main advantage of MRI of the lungs is its unique combination of morphological and functional assessment in a single imaging session. In this article, the authors review most technical aspects and suggest a protocol for performing chest MRI. The authors also describe the three major clinical indications for MRI of the lungs: staging of lung tumors; evaluation of pulmonary vascular diseases; and investigation of pulmonary abnormalities in patients who should not be exposed to radiation.

A Prospective Study

Abstract Introduction Modern magnetic resonance imaging (MRI) has a great sensitivity in detecting hip joint abnormalities, and because of its property of excellent visualization of soft tissue and nonionizing radiation, it is the modality of choice these days in not only adults but also pediatric musculoskeletal pathologies. Materials and Methods It was a prospective study performed in a tertiary care institute from 2016 to 2018. Total 64 cases with hip pathology attending orthopedics OPD (out patient department) and consenting to participate were included in the study. All the consenting participants were subjected to MRI scan. Results The most common pathology detected was avascular necrosis consisting of 28 cases. The next most common abnormality detected was infective arthritis, found in seven cases. Three patients were diagnosed with metastasis. Conclusion MRI is the diagnostic modality of choice for pathologies of hip for which radiographic and clinical findings are inconclusive. With MRI, one can stage the pathology to prognosticate and influence therapeutic decisions.

Diagnostic Modality

✓ The treatment of patients with Cushing disease and without magnetic resonance (MR) imaging evidence of Cushing disease (that is, negative MR imaging) is discussed in this paper. Magnetic resonance imaging is the diagnostic modality of choice in Cushing disease, but in up to 40% of these patients negative imaging can be caused by tumor-related factors and limitations in imaging techniques. In cases in which the MR imaging is negative, it is critical to make sure that the diagnosis of Cushing disease is correct. This can be accomplished by performing a complete laboratory and imaging workup, including dexamethasone suppression tests, imaging of the adrenal glands, and inferior petrosal sinus sampling when appropriate. If these evaluations suggest a pituitary source of the hypercortisolemia, then transsphenoidal surgery remains the treatment of choice. The authors favor the endoscopic approach because it gives a wider and more magnified view of the sella and allows inspection of the medial cavernous sinus walls. Radiosurgery is an effective treatment option in patients with persistent Cushing disease. When a target cannot be found on MR imaging, one can target the entire sellar region with radiosurgery.

Abstract Ten patients with neurosensory hearing loss and computed tomographic (CT) evidence of acoustic neuromas were evaluated with magnetic resonance imaging (MRI). Tumors ranged in size from 0.8 to 3.7 cm. With the use of spin echo pulse sequences, all tumors were identified by MRI and appeared as masses with signal intensities greater than that of cerebrospinal fluid and equal to or greater than that of brain stem. Two patients who previously had undergone operation for acoustic neuromas were evaluated with MRI. In one patient with CT evidence of tumor recurrence, the lesion could not be identified by MRI. MRI holds promise of becoming a primary diagnostic modality for the evaluation of acoustic neuromas.

Magnetic Resonance Imaging Mri

In the very short time since magnetic resonance imaging (MRI) was born it has gained surprisingly rapid and enthusiastic acceptance and has speedily proliferated, particularly in the United States and Western Europe. Magnetic resonance imaging (MRI) has successfully challenged computed tomography (CT) in all areas of the body where respiratory motion does not degrade the image (Steinberg, 1986). Newer techniques using a multiplicity of approaches are starting to close the gap between CT and MRI, even in the upper abdomen where the effects of respiratory motion are most pronounced. Although MR is already widely clinically applied and is an accepted everyday diagnostic modality in most large medical centres in the United States, it is not a mature modality. It is rapidly evolving, with whole new areas opening to investigation which will vastly broaden its applications.
