Introduction: Bacterial meningitis is an acute infectious inflammation of the protective membranes covering the brain. Its early diagnosis is vital because of its high morbidity and mortality. It is mostly diagnosed by a gold standard diagnostic tool i.e. Cerebrospinal Fluid (CSF) analysis. However, it is sometimes difficult and or impossible to do this procedure and an alternative diagnostic t...

Multiecho echo-planar imaging (EPI) was implemented for blood-oxygenation-level-dependent functional MRI at 1.5 T and compared to single-echo EPI with and without parallel imaging acceleration. A time-normalized breath-hold task using a block design functional MRI protocol was carried out in combination with up to four echo trains per excitation and parallel imaging acceleration factors R = 1-3...

background penile fracture is a relatively rare urologic emergency. it is defined as traumatic rupture in tunica albuginea of corpus cavernosum. traditionally, surgeon explores the penis in full-length by complete degloving of its skin and repairs any defect in the tunica. imaging modalities such as ultrasound and mri may be of help to reveal the exact site of tunica defect preoperatively for t...

Objective: Each imaging technique has a special application and usage, and should be used in the right situation. Physicians choose the type of imaging technique by considering the type of tissue and the benefits and disadvantages of the imaging method as well as its financial burden on the patient. The aim of this study was to estimate the cost of imaging tests performed in the emergency depar...

objectives to assess the diagnostic accuracy of pet-mri and mri alone for the detection of local recurrences of soft tissue sarcomas (sts) after initial surgical resection of the primary tumors. methods a total of 41 patients with a clinically suspected tumor relapse of sts underwent an 18f-fdg- pet-mri examination for assessment of local recurrence. two experienced physicians interpreted the m...

Objective(s): In view of somatostatin receptor (SSR) expression on cell membranes of the majority of neuroendocrine tumors (NETs), functional imaging exploiting analogs of SSR alongside the anatomical imaging is the mainstay of this diagnostic modality. In this prospective study, we assessed and directly compared the diagnostic parameters of 68Ga-DOTATATE PET/CT and 99...

Introduction: Recently, magnetic resonance spectroscopic imaging (MRSI), as a functional imaging method, has been used for clinical target volume definition. In this study, we used this method to define the target volume in prostate radiotherapy. Material and Method: In this study, we used images of 20 prostate cancer cases. MRSI and MRI images were fused with CT images. Then, treatment plannin...

symptomatic laryngeal chondrometaplasia is rare. to the best of our knowledge, there are only few case reports on laryngeal chondrometaplasia. the imaging appearance of this uncommon disease is even more rarely described. there are only two case reports describing its appearances in computed tomography (ct) and magnetic resonance imaging (mri). ultrasound (us) features have not been reported so...

metastases are the most common malignant hepatic lesions and considered to be the most frequent indication for imaging of the liver. the accurate detection and characterization of liver metastasis remains a critical issue at the initial diagnosis of primary cancer or during the course of patient treatment. in the recent years, the advent of highly efficient imaging modalities and new techniques...

objectives our objectives were to determine if: 1) imaging pattern at recurrence is associated with delayed diagnosis, and 2) appearance at recurrence can be predicted based on appearance at presentation. conclusion imaging appearance at baseline does not reliably predict imaging appearance at recurrence. therefore, a high index of suspicion for the infiltrative pattern is required in assessmen...
