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...

Organ Dose Evaluation for Head CT Scans using a Female Anthropomorphic Phantom

Fernanda Stephanie Santos, Priscila do Carmo Santana and Arnaldo Prata Mourao

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...

Intracranial Meningeal Hemangiopericytomas: Articles Review and Case Report

Jianliang Chen, Hengxing You, Yuanqiang Zhong, Xiaowen Lian and Zehong Wu

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...

Is there a Histopathologic Correlation of Prostatic PI-RADS Score 3 Lesions in Transition Zone in MRI with the Dynamic Contrast Curve Type? A Retrospective Single-Center Study

Sigmund Stuppner and Antonio Ruiu

Article Type: Research Article | First Published: May 17, 2019

Prostate cancer is the most frequent cancer type in males, but only about 20-30% of prostatic cancer originate in the TZ. The diagnosis is based on the prostate-specific antigen (PSA) screening in males over 40 years and transrectal or transperineal ultrasound-guided prostate biopsy. Prostate multiparametric MRI is indicated in patients with increasing PSA values (over 2, 5-3 ng/ml) and negative prostate biopsies and in patients with suspected trans-rectal palpation results....

Applications and Limitations of Magnetic Resonance Defecography in Evaluation of Pelvic Floor Dysfunction Disorders

Megha Kumra MBBS, Sushil G Kachewar MD, DNB, PH.D and Dilip L Lakhkar MD, DMRD

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...

DIBH-VMAT for Consolidation RT in Mediastinal B-NHL can Significantly Reduce Doses to OAR Report of Two Cases

Antje Fahrig, PD, Th Koch, Ch Heine, MSc, M Lenhart and L Fischer von Weikersthal

Article Type: Case Report | First Published: March 27, 2019

Consolidative radiotherapy after immuno-chemotherapy in localized bulky diffuse large B-cell lymphoma (DLBCL) patients significantly improves both, overall and progression-free survival and treatment is in principle curative. Therefore protection of organs at risk is highly relevant. Two 53-years and 18-years old patients with bulky mediastinal DLBCL were planned with and without deep inspiration breath-hold (DIBH) and volumetric modulated arc therapy (VMAT). DIBH reduced the doses to the heart ...

Adreniform Shape of Nonadenom Surrenal Lesion: Lymphoma

Ferhat Cuce

Article Type: Case Report | First Published: March 20, 2019

A 37-year-old male patient with a complaint of malaise applied to the internal medicine. The abdominal CT revealed an huge nonadenom adrenal mass lesion with 51 × 43 × 64 mm size. The significant finding was adreniform shape of gland was maintained in the lesion. The adrenal lymphoma should be considered in patients with adreniform shape of nonadenom adrenal lesion on CT. The MRI enables differentiation of adrenal adenomas from other adrenal malignancies, but specific diagnosis might not be ac...
