Lumbar Disc Degenerative Disorder among Patients Undergoing Magnetic Resonance Imaging in a Tertiary Care Centre: A Descriptive Cross-sectional Study

In a tertiary care hospital, magnetic resonance imaging revealed the presence of lumbar disc degenerative disease among patients undergoing magnetic resonance imaging. Methods: In a tertiary care hospital, a descriptive cross-sectional research was conducted in the Department of Radiodiagnosis and Interventional Radiology of a tertiary care center among patients with complaints of low back pain from May, 2021 to December, 2021. Result: The prevalence of lumbar disc degenerative disorder in 899 patients undergoing magnetic resonance imaging was found to be 155. Conclusions: The prevalence of lumbar disc degenerative disorder in patients undergoing magnetic resonance in our study was lower relative to other similar studies done in similar settings.

Endosonography and magnetic resonance imaging in the diagnosis of high anal fistulae – a comparison

Anal fistula is a benign inflammatory disease with variable etiology that occurs in about 10% of 100 000 adult patients. Fistulae surgery is also associated with the risk of damaging anal sphincters. Preoperative diagnosis of anal fistulae, endosonography, and magnetic resonance imaging all play a significant role in determining the surgical technique. The majority of fistulae are diagnosed in endosonography, but magnetic resonance is performed when the presence of high fistulae, particularly branching ones, is suspected, and recurrent is suspected. This paper was designed to compare the roles of the two examinations in the preoperative evaluation of high anal fistulae. The findings of endosonographic and magnetic resonance imaging investigations, which were conducted in 2011-2012 in 14 patients with high anal fistulae diagnosed intraoperatively, were reviewed retrospectively. Following contrast medium administration, magnetic resonance scans were conducted using a Siemens Avanto 1. 5 T scanner with a surface coil in T1, T1FS, FLAIR, T2 sequences, and T1 following contrast medium administration. The connection between endosonography and intraoperative assessment was 65%, according to magnetic resonance and intraoperative assessment u2013 41% and between endosonography and magnetic resonance u2013 53%. Endosonography in 67% of cases, magnetic resonance in 87% of cases, and the agreement between the two methods tested was 67%. Conclusions: Magnetic resonance is a more reliable method than endosonography in determining the type of high fistulae and the presence of branches.

Imaging of juvenile spondyloarthritis. Part II: Ultrasonography and magnetic resonance imaging

In children, sacroiliac joints and spine are extremely unusual; this is normal in adulthood; in adulthood, it is common. juvenile spondyloarthropathies were classified and radiographically illustrated in the first part of the paper. These tests are performed in patients with juvenile spondyloarthropathies to diagnose inflammatory lesions in peripheral joints, tendon sheaths, tendons, and bursae. In addition, magnetic resonance studies reveal subchondral bone marrow edema, which is also an early sign of inflammation. This essay explores a variety of inflammatory trends and discusses the diagnostic value of ultrasonography and magnetic resonance imaging.

Magnetic Resonance Imaging Findings of Intraspinal Tuberculoma in Children

paraphrasedoutput:Materials and Methods This study was designed to examine the innate and MRI findings of pediatric intraspinal tuberculoma and to determine the disease's potential cause. T1-weighted imaging, hypointense or isointense on T2WI, were mainly isointense on T1-weighted imaging, intratuberculoma, and extra tuberculoma. In intramural tuberculoma, a remarkable improvement was seen, and extracorporeous growth was evident in extratuberculoma. Ten tuberculoma patients died after antituberculous therapy, with intramedullary tuberculoma on T1WI, isointivity, or hypointensity on T2WI, and rim or obvious homogeneous growth. Some intraspinal tuberculomas, particularly intramedullary tuberculomas, may be attributed to the u201cparadoxical responseu201d system during the tuberculosis treatment.

Exercise-induced myocardial edema in master triathletes: Insights from cardiovascular magnetic resonance imaging

We wanted to determine changes in myocardial structure and function in master triathletes within 3 h after completing a full distance Ironman Triathlon run at 12 h, with a mean time of 12 h. Myocardial edema was defined as a region with an elevated T2 signal sensitivity of at least two SDs above the average myocardium. Global T2 SI was much higher in the postrace CMR and then presented with a close apical sparing pattern matched by the decrease of radial peak systolic strain of basal segments.

Effect of Moxibustion Treatment on Degree Centrality in Patients With Mild Cognitive Impairment: A Resting-State Functional Magnetic Resonance Imaging Study

paraphrasedoutput:MethodsA total of 47 patients with MCI were examined and 30 healthy controls were included in resting-state fMRI imaging scans, with a major difference being determined. Results were then compared with HCs and clinical signs to see the correlations between the neuroimaging findings and clinical signs. Conclusions:The improved Mini-Mental State Examination score was also positively related with increased DC in the right MFC and left MCC after moxibustion therapy, according to the common belief that moxibustion therapy may slow cognitive decline in patients with MCI.

Diagnostic imaging of psoriatic arthritis. Part II: magnetic resonance imaging and ultrasonography

Both magnetic resonance imaging and ultrasound within peripheral joints, tendon sheaths, and entheses are seen early in inflammation changes, as well as within peripheral joints. We review recent reports on psoriatic arthritis diagnosis based on magnetic resonance imaging and ultrasound, as well as some hypotheses on psoriatic arthritis etiogenesis, which have been published using magnetic resonance imaging.

Magnetic Resonance Imaging in Otosyphilis: A Rare Manifestation of Neurosyphilis

Computible tomography imaging showed destructive bone lesions surrounding the petrous temporal bone, middle ear, and mastoid region, with a pathognomonic pattern of bone damage depicted in the volume rendering technique images. In an adult patient with benign lesions of the petrous temporal bone, Otosyphilis should be considered as a distinguishing disease. MRI in otosyphilis has not been published to the best of our knowledge.

Cognitive decline in acoustic neuroma patients: An investigation based on resting-state functional magnetic resonance imaging and voxel-based morphometry

The mALFF value in the right caudate nucleus of the patients with left-sided AN and the right rectus region of the patients with right-sided AN soared in relation to the healthy individuals. In LAN patients, the mReHo values of the bilateral superior frontal gyrus and middle frontal gyrus were reduced. In LAN patients, the GMV values were higher in left fusiform gyrus, parahippocampal gyrus, calcularine gyrus, cuneus, and cuneus, as well as in the right fusiform gyrus and parahippocampal gyrus in RAN patients, relative to healthy controls. Cognitive decline in elderly patients in AN patients stimulates functional stimulation in several brain regions, thereby compensating for cognition loss. LAN caused more significant interference effect on the brain, leading to a more prominent interference effect in the brain, when RAN patients had more stable cerebral cortices.

Comparison between the coronal diameters of the cervical spinal canal and spinal cord measured using computed tomography and magnetic resonance imaging in Korean patients

Background: If the amount of the spinal cord in the epidural space can be determined under C-arm fluoroscopy during cervical epidural block, a safe entry point for the epidural needle can be determined. Methods We retrospectively reviewed the imaging results of 100 patients undergoing both cervical computed tomography and cervical magnetic resonance imaging at our hospital. Using the patients'U2019 cervical CT and MRI photographs, we measured the diameters of the spinal canal and spinal cord from the 3rd cervical vertebra to the 1st thoracic vertebra at each level. Conclusions Our results indicate that the cord to canal transverse diameter ratio can be used as a guide to minimize direct spinal cord injury in the case of cervical epidural block under C-arm fluoroscopy.
