Wunderlich Syndrome: A Rare Syndrome Caused by a Polyarteritis Nodosa
Leandro Tristao Abi-Ramia de Moraes, Monica Arnaldi and Sergio Furlan
Article Type: Case Report | First Published: December 30, 2019
Wünderlich syndrome (WS) is a rare condition, in which spontaneous nontraumatic renal hemorrhage occurs into the subcapsular and perirenal spaces and was described for the first time by Bonet in 1700. The etiology of the entity is very diverse, including benign or malign neoplasms, vascular diseases, infectious and inflammatory kidney diseases, and could be combined with some diseases. Clinically the syndrome is characterized by the classic Lenk's triad. We describe a case of WS in a 37-years-o...

Article Type: Research Article | First Published: December 09, 2019
One of the techniques of Nuclear Magnetic Resonance is Diffusion Tensor Imaging, which measures the speed of diffusion of extracellular water molecules found in tissues. Diffusion tensor imaging allows virtual dissections of functional white matter tracts in the human brain in vivo using regions of interest (ROI). The intrinsic trajectories of the olfactory pathway that can be identified using the diffusion- weighted magnetic resonance technique provide an important anatomical reference for the ...

Accurate assessment of locoregional response to neoadjuvant chemotherapy (NAC) is important for surgical planning, particularly in regard to management of the axilla. We evaluated the correlation between radiologic complete response (rCR) in the axilla on magnetic resonance imaging (MRI) and the likelihood of pathologic complete response (pCR) at the time of breast cancer surgery following NAC. Our institutional database was queried for patients who underwent NAC from 2010-2016 and had a preand ...

Study on the Variations of Image Density Index of MDCT for Healthy Lungs
Won-Bin Cha, Sok-Chan Yun, Chan-Ung Ri and Chol-Ho Chang
Article Type: Original Article | First Published: October 21, 2019
We selected several image density indices to establish CAD for prediction of biopsy in lung diseases. Our results suggested that significant difference was not observed in the image density indices between bilateral lungs at each slice level. Our own designed image indices may be reliable parameters in the establishment of CAD system and pathologic diagnosis for lung disease. There has been a rapid progress in the modality of CT since it was developed by Mr. Hounsfield. The earlier CT had been u...

Radiation Dose Reduction Comparing Dual Axis Rotational Coronary Angiography against Conventional Coronary Angiography in a Population with 100% Suspected Coronary Artery Disease: A Randomized Trial
Jorge Szarfer
Article Type: Research Article | First Published: September 16, 2019
We sought to compare the radiation dose, contrast volume, and procedure time between dual-axis rotational coronary angiography (DARCA) and conventional coronary angiography (CCA) techniques in a setting characterized by a prevalence of 100% suspected coronary artery disease. All-comers, prospective, randomized, open-label trial. Cine acquisition dose-area product (DAP), cumulative Air Kerma (AK), effective dose (E), fluoroscopic time, contrast volume, AK, cine acquisition DAP (CADAP), fluorosco...

Wearing seat belt makes driving safer. Nevertheless, it can cause particular lesions. In this case report, we present a woman suffering the characteristic safety belt lesions on bowel, spine and aorta. A 40-year-old woman is brought to the Emergency Room after a high-speed traffic accident. At the time of rescue, the patient was wearing a seatbelt. On examination, she presented tachycardia, hypotension and abdominal rigidity. A CT angiography of the abdominal aorta is requested for suspected aor...

An Atypical Case: Bilateral Radiation Necrosis

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...

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...
