giant uterine leiomyomas are extremely rare neoplasms and are challenging both diagnostically and therapeutically. a 49-year-old premenopausal female presented at our department complaining of abdominal pain and distention for several years. ultrasound (us), color doppler us, abdominal computed tomography imaging after administration of contrast material, and abdominal magnetic resonance imagin...

background: a solitary necrotic nodule (snn) of the liver is an uncommon lesion, which is different from primary and metastatic liver cancers. objectives: to analyze the classification, ct and mr manifestation, and the pathological basis of solitary necrotic nodule of the liver (snn) in order to evaluate ct and mri as a diagnosing tool. patients and methods: this study included 29 patients with...

In recent years, the development of neuroimaging techniques such as high-resolution magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), positron emission tomography (PET), or single photon emission tomography (SPECT) has promoted the identification of structural and functional characteristics underlying mental disorders to a great extent. In anxiety disorders, recent...

in this report, we have presented 18fdg-pet findings of organized hematoma of the maxillary sinus (ohms) that showed an increased fdg uptake in the peripheral rim of the mass with central photopenia. to our knowledge, this is the first case report in the literature reporting fdg-pet/ct findings of ohms. careful interpretation of metabolic (fdg-pet/ct) and anatomic (ct and mri) images should be ...

macrodystrophia lipomatosa is a rare congenital form of localized gigantism characterized by an increase in all mesenchymal elements, particularly fibroadipose tissue. mr imaging can be used to examine the soft tissue and detect the fibrous and fatty hypertrophy that characterizes this condition and also diagnose an associated fibrolipomatous hamartoma of the median or plantar nerve. we describ...

ABSTRACTNeuroimaging allows noninvasive evaluation of the anatomy, physiology, and function of the brain. It is widely used for diagnosis, treatment planning, and treatment evaluation of neurological disorders as well as understanding functions of the brain in health and disease. Neuroimaging modalities include X-ray computed tomography (CT), magnetic resonance imaging (MRI), single photon emis...

Bimodal imaging combines two imaging modalities in order to benefit from their advantages and compensate the limitations of each modality. This technique could accurately detect diseases for diagnostic purposes. Nanoparticles simultaneously offer diagnostic data via various imaging modalities owing to their unique properties. Moreover, bimodal nanoprobes could be incorporated into theranostic s...

desmoid tumor of breast is a rare benign, locally aggressive tumor with a high recurrence rate. it has been associated with scar from previous breast surgery or trauma. especially in breast cancer patients with previous operation history, it may simulate recurrent breast cancer clinically and radiologically. we presented multimodality imaging findings (ultrasound, computed tomography, magnetic ...
