Fine Adjustment

A normal disc–condyle relationship is crucial to the health and function of the temporomandibular joint. We herein introduce a novel technique that can precisely and rapidly restore the disc–condyle relationship. An initial bite rim was made, and the patient was instructed to wear this bite rim during magnetic resonance imaging (MRI) scanning. A quick MRI scan was performed, and the disc–condyle relationship and direction and vector of the displacement was measured. Adjustments to the mandible position were made on an articulator based on the measurements, after which a second bite rim was made. A second quick preview MRI scan was immediately performed, and the images were evaluated and measured again. Additional adjustments were made as needed, and the preview scan was repeated until an ideal disc–condyle relationship was achieved. Once a good disc–condyle relationship was acquired, the mandible position was recorded as the treatment mandible position, and a splint was fabricated. MRI visualization enabled precise and very fine adjustment of the disc–condyle relationship by articulating. This technique might help to simplify the clinical process and improve treatment effectiveness.

Prescribing Information

This is an update to the 2010 article published in Hospital Pharmacy on safety concerns involving transdermal patches and magnetic resonance imaging (MRI). Since publication of the original article, new brand and generic transdermal medications have become available and notable changes regarding the presence or absence of metallic content among existing transdermal formulations occurred. To update the tables within the article, Food and Drug Administration (FDA)-approved transdermal medications through October 2020 were researched in order to determine metallic content and procedures for reapplication after MRI, if applicable. Readers should consult the prescribing information or manufacturer for the most current information on use of transdermal medications in the MRI setting. Of note, manufacturers have not evaluated the use of transdermal products while patients undergo a MRI scan.

AbstractThe Kernohan-Woltman notch phenomenon is a paradoxical neurological manifestation consisting of a motor deficit ipsilateral to a primary brain injury. It has been observed in patients with brain tumors and with supratentorial hematomas. It is considered a false localizing neurological sign. Magnetic resonance imaging (MRI) scan has been the test of choice. The recognition of this phenomenon is important to prevent a surgical procedure on the opposite side of the lesion. The present case report describes a case of chronic subdural hematoma with a probable finding of the Kernohan-Woltman phenomenon, and it discusses its pathophysiology, imaging findings, treatment, and prognosis.

Meningiomas are known to be more common in females than males. They are also known in rare cases to grow in size during pregnancy, which can complicate its management. We describe a 31-year-old Caucasian woman who presented with blurring of her vision and diplopia during the third trimester of her pregnancy. Magnetic resonance imaging (MRI) showed a small left cavernous sinus meningioma. The patient was treated conservatively until her uncomplicated delivery. A postpartum MRI scan showed complete regression of the suspected meningioma. Currently the patient is contemplating a further pregnancy.

And Function

Heart disease is the number one cause of death in the United States [1]. Cardiac Magnetic Resonance Imaging (MRI) technology can be used to diagnose and evaluate a number of diseases and conditions such as coronary artery disease, damage caused by a heart attack, heart failure, and heart valve problems etc. Given the inherent difficulty in imaging the heart in motion, many efforts have been made to improve cardiac motion tracking and eliminate motion related artifacts. A dynamic heart phantom (DHP) capable of simulating true physiological motions is a valuable research tool for improving quality of MR images and determining critical diagnostic information. For instance, MR images have been used to quantify myocardial strain and estimate soft tissue material parameters and in turn to learn about cardiac structure and function [2–4]. In these studies, heart phantoms made of rubber like materials with known material properties are often used as a mean of validation.

Abstract Between 1987 and 1988, we utilized magnetic resonance imaging (MRI) in the diagnosis of seven cases of “subacute” pituitary apoplexy. that is, intra-adenomatous pituitary hemorrhage associated with clinical symptoms atypical of acute pituitary apoplexy. These symptoms lasted longer than 24 hours and included visual changes in four patients, headache in five, and seizures, endocrine dysfunction, and oculomotor palsy in one each. Estimates of the ages of the hemorrhages were also possible based on characteristics on the MRI scan and ranged from 48 hours to more than 14 days. Four of our seven patients underwent transsphenoidal decompression at which time the presence of intratumoral hemorrhage was confirmed. The remaining three patients have been followed as outpatients with serial MRI examinations and have shown improvement in clinical symptoms and stabilization of the radiological picture. From our series of patients, it is now apparent that the MRI scan is an invaluable tool in identifying this subacute form of intra-adenomatous pituitary hemorrhage and has proven especially useful as a means of therapeutic planning and follow-up care in patients presenting with symptoms not typical of classic pituitary apoplexy.

A case of synchronous cystic teratomas presented with the complaints of a slow-growing facial mass and forward protrusion of the right eye since birth. The patient was examined thoroughly and subjected to magnetic resonance imaging (MRI) scan. The MRI scan revealed the presence of two separate cysts in the right orbit and right temporal fossa. The patient was operated by a combined effort of ophthalmologists and otorhinolaryngologists. The cysts were excised and subjected to pathological examination. The histopathological survey revealed both the cysts to be mature cystic teratomas similar to each other. This coexistence of a primary temporal fossa teratoma with an orbital teratoma is the first of its kind and to the best of our knowledge has not been reported before.

ABSTRACTA 60-year-old patient with a clinical diagnosis of schizophrenia underwent a magnetic resonance imaging (MRI) scan related to the evaluation of isolated seizures that emerged while medicated with clozapine. Unexpectedly, the MRI scan revealed evidence of asymmetric and enlarged cerebral ventricles that were interpreted as congenital in origin. The presence of both congenital lateral ventricular asymmetry and ventriculomegaly may interact to increase risk of schizophrenia. The history and clinical features, including cognitive testing, of the illustrative patient are presented.
