25. Evaluation of 10-minute post-injection 11C-PiB PET and its correlation with 18F-FDG PET in older adults who are cognitively healthy, mildly impaired, or with probable Alzheimer’s disease
Objective: Positron emission tomography (PET) allows in vivo evaluation of molecular targets in neurodegenerative diseases, such as Alzheimer’s disease. Mild cognitive impairment is an intermediate stage between normal cognition and Alzheimer-type dementia. In vivo fibrillar amyloid-beta can be detected in PET using [11C]-labeled Pittsburgh compound B (11C

26. Robotic-assisted nephrectomy with level II IVC thrombectomy using Rummel Tourniquets
ABSTRACT Background: Inferior vena cava (IVC) invasion from renal cell carcinoma (RCC) occurs at a rate of 4-10% (1). IVC thrombectomy (IVC-TE) can be an open procedure because of the need for handling of the IVC (2). The first reported series of robotic management of IVC-TE started in 2011 for the management of Level I - II thrombi with subsequent case rep

27. Robotic excision of vaginal pouch in ovotesticular disorder of sexual development
ABSTRACT Purpose: Ovotesticular disorder of sexual development (DSD) is the rarest of DSDs with an incidence of 1:20000 (1). Management of vaginal pouches in such cases is warranted for symptomatic presentations and laparoscopy is considered the gold standard treatment (2). We report a rare case of robotic excision of a large symptomatic vaginal pouch in a

28. Cushing disease due to a somatic USP8 mutation in a patient with evolving pituitary hormone deficiencies due to a germline GH1 splicing variant
SUMMARY We present the unique case of an adult Brazilian woman with severe short stature due to growth hormone deficiency with a heterozygous G to T substitution in the donor splice site of intron 3 of the growth hormone 1 (GH1) gene (c.291+1G>T). In this autosomal dominant form of growth hormone deficiency (type II), exon 3 skipping results in expression of

29. Measurement of retina/choroid complex perfusion with magnetic resonance imaging in eyes with acute primary angle-closure
RESUMO Objetivos: Mensurar a perfusão do complexo retina/coróide com ressonância magnética em olhos com fechamento angular primário agudo (FAPA). Métodos: Três sequências de ressonância magnética, duas anatômicas e uma de perfusão com gadolínio, foram adquiridas em pacientes com fechamento angular primário agudo. Regiões de interesse foram d

30. Frequency of lipid-poor adrenal adenomas in magnetic resonance imaging examinations of the abdomen
Resumo Objetivo: Estimar a frequência de adenomas pobres em lipídios (APLs) em exames de ressonância magnética (RM). Materiais e Métodos: Investigaram-se, retrospectivamente, as lesões adrenais em exames de RM realizados de janeiro de 2016 a dezembro de 2017. Um total de 2.014 pacientes foi submetido a exames abdominais e, após exclusões, 69 pacien

31. Robotic management of congenital urethra-vaginal fistula with transverse vaginal septum
ABSTRACT Introduction: The transverse vaginal septum (TVS) with congenital urethra-vaginal fistula (CUVF) is a rare anomaly of the mullerian duct (1, 2). Incomplete channelling of the vaginal plate, or an abnormality in the fusion of the vaginal component of mullerian duct with the urogenital sinus results in TVS (1, 3, 4). High CUVF occurs due to the persi

32. Audio-vestibular and radiological analysis in Meniere’s disease
Abstract Objective: Intravenous gadolinium-enhanced inner ear magnetic resonance imaging (IV Gd-enhanced inner ear MRI) is a new technique for diagnosing Meniere’s disease (MD). Vestibular tests have also long been used forMD, but which tests should be included in the oto-neurological test battery remains controversial. The evaluation method to be used to

33. Computed tomography with low-dose radiation versus standard-dose radiation for diagnosing fractures: systematic review and meta-analysis
BACKGROUND: Computed tomography (CT) accounts for 13% of all radiological examinations in the United States and 40-70% of the radiation that patients receive. Even with the advent of magnetic resonance imaging (MRI), CT continues to be the gold standard for diagnosing bone fractures. There is uncertainty as to whether CT with a low radiation dose has a frac

34. Apoplexy in sporadic pituitary adenomas: a single referral center experience and AIP mutation analysis
ABSTRACT Objective: To analyze the clinical, laboratory, and radiological findings and management of patients with clinical pituitary apoplexy and to screen for aryl hydrocarbon receptor-interacting protein (AIP) mutations. Subjects and methods: The clinical findings were collected from the medical records of consecutive sporadic pituitary adenoma patients

36. Multidisciplinary Approach to Right Ventricular Myxoma
Abstract Right ventricular (RV) myxoma that obstructs the RV outflow tract is rare. Multimodality imaging is crucial due to the curved and triangular shape of the RV anatomy. Incomplete resection by the right atrial approach in cardiac myxomas may be prevented by preoperative imaging with echocardiography, computed tomography and magnetic resonance imaging t
