Article Type: Case Report | First Published: August 28, 2019
Temporal lobe necrosis (TLN) is often seen in nasopharyngeal carcinoma secondary to less frequent other extracranial malignancies. Radiotherapy is one of the most frequently used methods in the treatment of nasopharyngeal carcinoma. This method can have many side effects. One of the side effects associated with high-dose radiotherapy is cerebral necrosis. Cerebral radiation is the sum of the dose of radiotherapy given as the most important risk factor for necrosis. It is often seen within the fi...

Diagnostic Efficiency and Reproducibility of Hysterosalpingography
Shimaa Abdalla Ahmed and Hesham Abo Taleb
Article Type: Original Article | First Published: August 10, 2019
200 infertile females underwent hysterosalpingography, hysteroscopy and/or laparoscopy as part of an infertility work up. HSG examinations were retrospectively reviewed by three radiologists, we compared inter-observer variability, differences between the two results of reading the same examination after three months were compared to calculate intra-observer variability. HSG is more accurate in tubal evaluation than the uterine cavity assessment. HSG interpretation is somewhat subjective, althou...

Dosimetry and Protocol Optimization of Computed Tomography Scans using Adult Chest Phantoms
Arnaldo Prata Mourao, Wadia Namen Aburjaile, Phd and Fernanda Stephanie Santos
Article Type: Original Article | First Published: June 22, 2019
Computed Tomography (CT) has become an important tool for diagnosing cancer and to obtain additional information on different clinical issues. The radiation dose values in computed tomography depend on the scan acquisition protocol. Today, it is a very fast, painless and noninvasive test that can be performed high quality images. Therefore, it is indispensable to improve protocols, seeking smaller doses, without impairing the diagnostic quality of the image. The doses received are related with r...

Article Type: Original Article | First Published: June 21, 2019
Computed Tomography (CT) has become an important tool for diagnosing cancer and to obtain additional information on different clinical issues. Today, it is a very fast, painless and noninvasive test that can be performed high quality images. However, CT scans usually require a higher radiation exposure than a conventional radiography examination. Head CT scans are used for diagnosis of traumatic head injuries, infections and other diseases with instability. Based on this information, three head ...

Nephroenteric Fistula after Lithotripsy-A Rare Complication
D Campos Correia, MD, Ricardo M Antunes and P Ferreira
Article Type: Case Report | First Published: June 12, 2019
Nephroenteric fistulas are rare and generally occur as a result of chronic inflammation, ischemia or necrosis. Nephrectomy and primary closure of the fistulous tract currently represent the mainstay of treatment for non-functioning kidneys but kidney preservation should be attempted in cases of traumatic fistulae. The authors report a case of a 69-year-old female with an infected subcapsular renal haematoma and a fistulous tract to the duodenum following ureteroscopic laser lithotripsy of a righ...

Article Type: Case Report | First Published: June 12, 2019
Intracranial meningeal hemangiopericytomas (HPCs) represent a rare and aggressive intracranial neoplasm located along the dural sinuses, tend to recur and metastasize, and account for less than 1% of intracranial tumours and approximately 2~4% of all meningeal tumors. We discuss herein the dynamic of HPCs and review the literatures from its clinical symptoms, imaging features, histopathological features, differential diagnosis and treatment and prognosis, and present a case of a 35-year-old male...

Article Type: Research Article | First Published: April 06, 2019
Functional disorders of the pelvic floor are common healthcare problems owing to increased incidence of obesity, pelvic surgeries, childbirth, heavy physical exertion etc. In the past, fluoroscopic defecography was used in their diagnosis, but it had its limitations like radiation exposure. Endoanal sonography and Magnetic Resonance Imaging (MRI) were also used to assess the pelvic pathologies but they could not assess the pelvic floor function. Magnetic Resonance Defecography (MRD) is a new mod...
