Kidney stone disease has become more common in children, but it remains non diagnosed in a significant proportion of patients, due to a lack of notable signs and symptoms. All children with colicky abdominal pain or microscopic hematuria should be examined thoroughly for urolithiasis. Patients’ histories in terms of family, medical, and drug and a thorough physical examination are require...

Uterine leiomyoma is the most common benign tumor of genital tract. The etiology of myomas is unknown. Leiomyoma shows a broad spectrum of radiographic appearances depending on the number, size, and location of the tumor. The diagnostic method for uterine leiomyomas is based primarily on the clinical situation. Despite of the varied diagnostic options such as; transvaginal sonography, sonohyste...

The diagnosis of prosthetic valve endocarditis continues to present a diagnostic challenge, due to the lower sensitivity of the modified Duke criteria and a higher percentage of negative or inconclusive echocardiography results. Diagnostic delay might result in significant morbidity/mortality. Imaging modalities like 2-[18F]fluoro-2-deoxy-D-glucose positron emission tomography/comput...

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...

introduction: due to the cell labeling potentials of various metal-maltol complexes, the idea of developing a possible cell labeling imaging agent using single photon emission computed chromatography (spect) with[111in]-maltolate complex has been investigated. methods: [111in] labeled 3-hydroxy-2-methyl-4h-pyran-4-onate ([111in]-maltolate) was prepared using freshly prepared [111in]incl3 and ...

Background: To retrospectively evaluate whether quantitative information derived from spectral imaging can improve the differential diagnosis of pancreatic cystic masses including pancreatic solid pseudopapillary epithelial neoplasms (SPENs), mucin- producing cysts and pseudocysts. Materials and Methods: From June 2015 to October 2017, 56 patients (22 pseudocysts, 18 mucin-producing cysts and 1...

introduction: although pet scanning using f-18[fdg] is considered the superior radiotracer for tumnor imaging, gallium-67 is still in use for some malignancies such as lymphoma and hepatoma. one of the strategies to improve the diagnostic accuracy of gallium is to perform spect which is reported to be more sensitive compared to planar imaging. in this study we compared the sensitivity of spect ...

Radiation from imaging diagnostic had caused many detrimental effects to patients. Imaging diagnostic is the largest manmade source of radiation exposure. Doseresponse models have aided the study of effects of radiation from imaging diagnostic. Certain imaging tools have caused more radiation hazard towards patients such as computed tomography. Non-ionizing radiation imaging modalities have rep...

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...
