S. Refahi,M. Pourissa,L. Dadashi
Iranian Journal of Radiology , 2008,
Abstract: Background/Objective: MRI FLAIR sequence has good results in comparison with MRI standard se-quences. We decided to study the findings of the epi-leptic patients in FLAIR sequence of MRI."nPatients and Methods: 104 patients with the history of previous seizure were studied. The brain MRI in these patients was performed at T1, T2, PD, and FLAIR sequences. "nResult: In our study, 63.47% of patients had abnormal MRI findings. Space occupying lesions were seen in 24%, brain vascular lesion in 16.35%, hippocampal sclerosis in 6.73%, brain degenerative lesion in 3.85%, sequel of old lesion in 6.73%, brain develop-mental malformation in 1.92%, and other lesions in 3.85%."nConclusion: FLAIR sequence of MRI has good results in comparison with standard MRI sequences in rec-ognizing the cerebral lesions at epileptic patients, es-pecially in low grade tumors. Seizure is one of the common demonstrations of these tumors. FLAIR se-quence is also a challenge on subtle localization re-covery, temporal lobe epilepsy.

Neurology India , 2005,
Abstract: Neuro-cysticercosis (NCC) and Japanese encephalitis (JE) are common in tropical countries. Two cases of NCC with coexistent JE are presented, which share same socio-demographic and ecologic factors and have the same intermediate host (pig). Patients were on treatment for NCC and presented in comatose state. Sudden clinical deterioration of a patient with NCC should warrant a search for coexistent JE. We report findings of magnetic resonance spectroscopy and diffusion-weighted imaging of the JE.

Abstract: Adnexial torsion is an unusual event, but a major cause of abdominal pain in women. It is often associated with ovarian tumor or cyst, but can occur in normal ovaries, especially in children. The twisting of adnexial structures may involve the ovary or tube, but frequently affects both. In most cases, it is unilateral, with slight predilection for the right side. In imaging findings, increased ovarian volume and adnexial masses are observed, with reduced or absent vascularization. In cases of undiagnosed or untreated complete twist, hemorrhagic necrosis may occur leading to complications; in that, peritonitis is the most frequent. Early diagnosis helps preventing irreversible damage with conservative treatment, thereby saving the ovary. Limitations in performing physical examination, possible inconclusive results in ultrasound and exposure to radiation in computed tomography makes magnetic resonance imaging a valuable tool in emergency assessment of gynecological diseases. The objective of this study was to report two confirmed cases of adnexial twist, emphasizing the contribution of magnetic resonance imaging in the diagnosis of this condition.

Iranian Journal of Radiology , 2008,
Abstract: Epilepsy is a common neurological affliction of children. It carries an estimated annual incidence of up to one per 1,000, and a prevalence of up to 5 per 1,000 children. Children suffering from epilepsy have a significantly increased mortality rate. The major causes of death are the underlying cause of the epilepsy itself, associated neurological compromise, injuries, and status epilepticus."nNeuroimaging techniques have advanced the diagnosis, management, and understanding the pathophysiology of underlying the epilepsies. MRI is the technique of choice for investigation of patients with seizure disorders. MRI provides excellent anatomic information and tissue contrast, resulting in high sensitivity. MRI studies should be customized to answer the appropriate clinical questions. Functional imaging techniques including magnetic resonance spectroscopy and functional MRI are becoming increasingly important in the investigation and management of patients with seizures. These techniques permit noninvasive assessment of the epileptic substrate, functional status, ictal activity, blood flow changes, me-tabolism, and neuroreceptors. Application of these new techniques promises to advance our understanding and treatment of seizures in children. In this presentation we will address the MR findings of epilepsy in children.

Journal of Medical Case Reports , 2012, DOI: 10.1186/1752-1947-6-282
Abstract: Introduction Primary lymphoma of the liver is an extremely rare finding, with the few such cases reported in the literature to date describing indeterminate imaging findings, being focused more on computed tomography. To the best of our knowledge, there is no prior report describing magnetic resonance imaging scan findings with such a lesion. In the case reported here, magnetic resonance imaging gave us the opportunity to ascertain the correct diagnosis, confirmed by histopathology, thus avoiding unnecessary surgery or other treatments. Although this condition is rare, knowledge of magnetic resonance imaging findings will be invaluable for radiologists and other medical subspecialties that may face such cases in the future in helping to provide adequate management for affected patients. Case presentation A focal lesion was incidentally detected by ultrasound in a 75-year-old asymptomatic Albanian man being treated for benign hypertrophy of prostate. Chest and abdomen computed tomography scans did not reveal any abnormal findings besides a solid focal lesion on the right lobe of the liver and a mild homogenous enlargement of the prostate gland. Subsequently, magnetic resonance imaging of the upper abdomen was performed for better characterization of this lesion. Our patient was free of symptoms and his laboratory test results were normal. Conclusions The magnetic resonance imaging scan results showed some distinctive features that helped us to make the correct diagnosis, and were thus very important in helping us provide the correct treatment for our patient.

World Journal of Radiology , 2012, DOI: 10.4329/wjr.v4.i3.90
Abstract: AIM: To evaluate magnetic resonance imaging (MRI) features of different types of gray matter heterotopia. METHODS: Between June 2005 and December 2009, the medical records and MRI studies of patients with gray matter heterotopia were reviewed. The MRI morphologic findings of heterotopia were recorded along with the presence and type of associated cranial malformations. Available clinical and electrophysiological data were also recorded. RESULTS: 20 patients were included in the study. Their ages ranged from 9 mo to 39 years with a mean age of 15 years. All patients suffered from epileptic seizures. According to the location of heterotopia, patients were classified into three groups: subependymal (12), subcortical (5) and band (3) heterotopia. CONCLUSION: MRI was useful in diagnosing and differentiating between various types of gray matter heterotopia. The severity of clinical manifestations of heterotopia was related to the location and pattern of heterotopia. Determination of heterotopia type and its extent is useful for management planning and predicting prognosis.

World Journal of Radiology , 2011,
Abstract: Staging of rectal cancer is essential to help guide clinicians to decide upon the correct type of surgery and determine whether or not neoadjuvant therapy is indicated. Magnetic resonance imaging (MRI) is currently one of the most accurate modalities on which to base treatment decisions for patients with rectal cancer. MRI can accurately detect the mesorectal fascia, assess the invasion of the mesorectum or surrounding organs and predict the circumferential resection margin. Although nodal disease remains a difficult radiological diagnosis, new lymphographic agents and diffusion weighted imaging may allow identification of metastatic nodes by criteria other then size. In light of this, we have reviewed the literature on the accuracy of specific MRI findings for staging the local extent of primary rectal cancer. The aim of this review is to establish a correlation between MRI findings, prognosis, and available treatment options.
Magnetic Resonance Imaging Findings in Intracranial Dural Metastases  [PDF]
Journal of Neurological Sciences , 2010,
Abstract: Background and Methods: Intracranial dural metastases are found in 9% of patients with advanced systemic cancer at autopsy. Detection of dural metastasis is as important as the systemic control of the cancer. We conducted a retrospective review of 25 cancer patients with dural metastasis from 2008 to 2010 and compared the cranial magnetic resonance imaging findings with clinical features.Results: Seventy-six percent of the parients were women; the mean age at diagnosis was 54 years. Breast (56%), prostate (12%) , lung (12%) and colon (8%) cancers were the most frequent tumors associated with dural metastasis. Unusual tumor types included chronic myelocytic leukemia (4%), carcinomas of bladder (4%), endometrium (4%). Dural metastasis were usually lineer, multiple, plaque-like and subdural lesions; coexisting with bone (84%) or skull metastasis (60%). On imaging, 44% patients had metastases of the brain parenchyma, 60% of lung and 64 % liver.Conclusions: Dural metastasis may arise from skull metastases or hematogeneous spread. Dural metastasis in the course of a spreading cancer is very important clinical problem for clinicians. Prompt diagnosis with neuroradiological methods is crucial. Large scale prospective studies are required to determine the true incidence and specific patterns of dural metastasis that could be specific to different cancer types.

Abstract: The efficacy and the tolerance of the AEDs have been extensibly studied in the past, however the effects of them on the EEG activity of epileptic patients have been scarcely studied. Eslicarbazepine is a third generation blocker-sodium channels AED associated with a high reduction in the rate of partial seizures in epileptic patients. We designed an open label, non control study to determine the effects of Eslicarbazepine on the EEG activity of EP with focal seizures in a 12-week follow up. The EP with focal paroxystical activity enrolled in this study showed a statistical significant reduction in the rate of monthly seizures when Eslicarbazepine 800 mgs was added to a previous AED compared to those patients who only received an increase of the AED in monotherapy, concomitantly, EP treated with ESL added to a previous AED showed a statistically significant reduction in the mean occipital frequency and voltage amplitude in the central and parietal regions in the twelfth-week EEG compared to the control group.
