Introduction. Observation of open-ring enhancement in magnetic resonance imaging (MRI) is considered a specificity marker for diagnosing pseudotumoral multiple sclerosis (MS). This finding is of great value in the differential diagnosis of tumefactive lesions. Case Report. We describe a 55-year-old white woman, with previous history of ovarian cancer and recent history of fatigue and bilateral ...

Introduction Magnetic resonance imaging (MRI) is a valuable diagnostic method for many cardiovascular diseases. To date, patients with pacemakers are contra-indicated for cardiac MRI exams due to several effects that can occur during the MRI procedure: a) heating of the lead-tip, and b) less hazardous sensing errors and device malfunctions. Almost all measurements on MRI pacemaker compatibility...

presentation of an unusual case of cerebral aspergillosis in an immune competent patient who was treated successfully but symptoms and signs of a demyelinating process following initial recovery has been occurred. a 29-year-old male with focal seizure. brain mri revealed small multiple hemispheric and dural lesions. an open biopsy was conducted. histological evaluation revealed hyphe-like struc...

Mediastinal epidermoid cyst is a rare condition that is considered as a congenital disorder. Various manifestations from asymptomatic cases to serious symptoms may be found in these patients. However, some cases may be diagnosed incidentally. Here, we report an old man with recurrent pneumonia who demonstrated symptoms of respiratory distress and chest pain. The high resolution computed tomogra...

This paper preliminarily reports the robotic system working inside the gantry of vertical field Open MRI. This manipulator is new in terms of the application to vertical field Open MRI, cost effectiveness, accuracy and stiffness sufficient for endoscope manipulation. The endoscope manipulation for trans-nasal neurosurgery under MR-guidance was selected as the sample task. The endoscope operatio...

Although mice are the dominant model system for studying the genetic and molecular underpinnings of neuroscience, functional neuroimaging in mice remains technically challenging. One approach, Activation-Induced Manganese-enhanced MRI (AIM MRI), has been used successfully to map neuronal activity in rodents. In AIM MRI, Mn(2+) acts a calcium analog and accumulates in depolarized neurons. Becaus...

Aim. The aim of the present study was to perform MRI in patients after ventral hernia mesh repair, in order to evaluate MRI's ability to detect intra-abdominal adhesions. Materials and Methods. Single-center long term follow-up study of 155 patients operated for ventral hernia with laparoscopic (LVHR) or open mesh repair (OVHR), including analyzing medical records, clinical investigation with p...

Magnetic resonance imaging (MRI) is a cutting edge imaging modality in detecting diseases and pathologic tissue. The superior soft tissue contrast in MRI allows better definition of the pathology. MRI is increasingly used for guiding, monitoring and controlling percutaneous procedures and surgery. The rapid development of interventional techniques in radiology has led to integration of imaging ...
