Magnetic Resonance Imaging Mri

This is a case study of a 47-year-old Caucasian male whose chief concern was left lower leg swelling for 1 month. A unilateral lower extremity venous duplex examination was performed. The results concluded that the distal femoral vein was occluded to the distal popliteal vein. Incidentally, a hypoechoic region in the distal thigh near the distal femoral artery was noted by the technologist. The patient was placed on anticoagulation and was told to return for further examination if there was no relief. Three months later, the patient continued to experience lower left leg swelling and returned for another sonogram. The hypoechoic region was seen again in the distal thigh and remained occluded. A computed tomographic arterial (CT-A) and magnetic resonance imaging (MRI) were ordered for further investigation of the hypoechoic area. The CT-A and the MRI revealed the presence of a mass in the distal thigh. The mass was biopsied and diagnosed as a leiomyosarcoma, grade 1. The mass caused the compression and occlusion of the distal femoral vein. The mass was removed, along with a portion of the distal femoral artery due to involvement of the artery within the mass. The artery was repaired with a graft.

Powerful Diagnostic Tool

Magnetic resonance imaging (MRI) is a unique and powerful diagnostic tool that provides images without ionizing radiation and, at times, can be the only modality to properly assess and diagnose some pathologies. Although many patients will need an MRI in their lifetime, many of them are still being unjustly denied access to it due to what were once considered absolute contraindications, including MR nonconditional pacemakers and implantable cardioverter-defibrillators. However, there are a number of large studies that have recently demonstrated that MRI can safely be performed in these patients under certain conditions. In addition, there are an increasing number of novel cardiac devices implanted in patients who may require an MRI. Radiologists need to familiarize themselves with these devices, identify which patients with these devices can safely undergo MRI, and under which conditions. In this article, we will review the current literature on MR safety and cardiac devices, elaborate on how to safely image patients with cardiac devices, and share the expertise of our tertiary cardiac institute.

Background: An ischemic stroke takes place when a blood vessel supplying the brain is blocked and blood circulation to a part of the brain is damaged. A lacunar stroke occurs due to one of the arteries that provide blood to the brain's deep structures is blocked. Case Study: A 55-year-old male patient have right cerebrovascular accident (CVA) with left hemiparesis on 16th of August 2019. Normal result was seen by brain Computed Tomography (CT) scanning. Magnetic Resonance Imaging (MRI) brain was done resulted in hyperintense lesion in right pons and foci and Magnetic Resonance Angiography (MRA) was done and resulted in severe basilar artery stenosis.

Introduction: Most pregnant women will experience a normal pregnancy process. However, there are some complications that may occur during pregnancy, including intra-abdominal pregnancy. Intra-abdominal pregnancy, or pregnancy outside of the uterus, are commonly reported besides abortion, pregnancy-induced hypertension (PIH) and gestational diabetes mellitus (GDM). Thesecomplications are believed to be the main cause of maternal and perinatal death. Therefore, the use of appropriate diagnostic imaging inthe management of obstetric cases should be focused.Objective: This case study intended to evaluate the use of magnetic resonance imaging (MRI) in managing intra-abdominal pregnancy.Case Presentation: The study focused on one case with intra-abdominal pregnancy which continued into the second trimester. A 30-year-old woman, G2 P0+1 at 12-13 weeks’ gestation was presented to a public hospital complaining of recurrent epigastric pain with no history of vaginal bleeding. An MRI was performed and the mother was identified as having an intraabdominal pregnancy. Urgent laparotomy was done. Intraoperative finding noted hematoperitoneum with active bleeding seen from the placenta that adhered to the omentum. Partial omentectomy was done. The foetus in about 14 week’s gestation was seen and removed. Case studies have proven that the option to perform an MRI on a suspected intra-abdominal pregnancy can help provide information to establish an accurate diagnosis and appropriate patient care management.Conclusion: The use of MRI is highly recommended for all cases that are expected to experience intra-abdominal pregnancy as it will save the patient as well as avoiding obstetric complications.International Journal of Human and Health Sciences Supplementary Issue: 2021 Page: S16

In this case study, we presented the radiological characteristics of a 43-year-old female patient diagnosed with Multiple Sclerosis (MS). Following mitoxantrone administration, she developed liver failure. Magnetic Resonance Imaging (MRI) revealed multiple periventricular lesions in T2 and bilateral involvement of putamen and Globus Pallidus (GP) areas in T1 sequences.

This case study aims to apply the processes of decision-making for magnetic resonance imaging (MRI) as a diagnostic examination for a patient with cardiac pacemaker admitted to a private hospital in the capital of Indonesia. It also aims to examine and evaluate the case of a 53-year-old mother who had a heart abnormality that has a pacemaker for one year and was diagnosed to do an MRI examination because of a suspected tumor on the wrist area.The three basic models of decision-making — the descriptive, prescriptive and normative — were applied. The prescriptive used the information processing theory, while the normative used decision trees as decision options and lastly, the descriptive used intuition and pattern recognition.Dominantly, the prescriptive model for decision-making is more appropriate for this case.  The descriptive decision-making model, using intuition however, helped in supporting the intuitive hypothesis.  Lastly, the normative model of decision-making played an important role but was not likely effective.
