Magnetic resonance imaging of ankle impingement syndrome: iconographic essay

Radiologia Brasileira — Fri, 12 Mar 2010 15:28:55 +0100

A síndrome do impacto do tornozelo é uma condição dolorosa causada por atrito de tecidos articulares, que é tanto causa quanto consequência de uma biomecânica alterada desta articulação. A sua principal causa são as lesões pós-traumáticas, principalmente lesões ligamentares, resultando em dor crônica no tornozelo. Do ponto de vista anatômico e clínico, estas síndromes são classificadas em: ântero-lateral, anterior, ântero-medial, póstero-medial e posterior. A ressonância magnética é um ótimo método diagnóstico para demonstrar as alterações ósseas e as partes moles dos vários tipos de impacto do tornozelo, fornecendo dados que auxiliam não só na comprovação desse diagnóstico, como na diferenciação com outras causas de dor articular.

Magnetic resonance imaging in lower urinary tract endometriosis: iconographic essay

Radiologia Brasileira — Fri, 24 Jul 2009 11:37:22 +0100

Endometriose é definida como a presença de tecido endometrial funcionante fora da cavidade endometrial e do miométrio. É uma doença comum, de causas multifatoriais, porém o envolvimento do trato urinário baixo é raro. A ressonância magnética tem elevada sensibilidade, especificidade e acurácia no diagnóstico da endometriose do trato geniturinário baixo, principalmente por permitir a identificação das lesões de permeio a aderências e a avaliação da extensão das lesões subperitoneais. Neste estudo são ilustrados, sob a forma de ensaio iconográfico, os principais achados à ressonância magnética do envolvimento por endometriose do trato urinário baixo.Endometriosis is defined as the presence of functional endometrial tissue outside the endometrial cavity and myometri...

Radiomorphological study of the peroneus longus tendon adjacent to the cuboid bone

Radiologia Brasileira — Fri, 24 Jul 2009 11:37:22 +0100

CONCLUSION: All the specimens presented focal thickening of the tendon under the arc of the cuboid bone. However, quantitative analysis of both specimens submitted to histological evaluation demonstrated that the tendon consisted of fibrocartilaginous tissue lined by hyaline cartilage on the surface of contact with the bone. Thus, under the morphological point of view, fibular ossicle was found in 28% of cases, and, under the radiographic point of view, in 26%. (Source: Radiologia Brasileira)

Proton spectroscopy study of the masseter in patients with systemic sclerosis

CONCLUSION: Lower lactate levels were observed in the patients with systemic sclerosis (groups I and II). Choline levels were increased in the patients with mandibular osteolysis (group I). Creatine/choline, lipid/lactate and choline/lipid ratios were different among the three groups. Further studies are necessary to understand the role played by the masseter in the development of mandibular osteolysis. (Source: Radiologia Brasileira)

Evaluation of agreement between transvaginal ultrasonography and magnetic resonance imaging of the pelvis in deep endometriosis with emphasis on intestinal involvement

Radiologia Brasileira — Thu, 25 Jun 2009 08:18:15 +0100

CONCLUSION: The intermethod agreement has not been good for lesions in the rectosigmoid junction, considering that ultrasonography has detected a higher number of lesions in this region, but a lower number of lesions in the pelvis as compared with magnetic resonance imaging. The global comparative analysis has demonstrated no statistically significant intermethod difference in the detection of lesions. Low cost, good tolerability and high availability make ultrasonography a valuable diagnostic tool in cases of deep endometriosis. (Source: Radiologia Brasileira)

3D conformal external beam radiation therapy for prostate carcinoma: an experiment of Instituto do Radium de Campinas with 285 patients

Radiologia Brasileira — Thu, 25 Jun 2009 08:18:15 +0100

CONCLUSION: The first experiment with 3D conformal radiation therapy reported in Brazil allowed high radiation doses with acceptable levels of urinary and rectal toxicity. Pre-3D conformal radiation therapy transurethral resection of prostate may determine a higher risk for post-irradiation grade 2-3 late urinary toxicity. At the tomography planning, the reduction of the radiation dose to < 70 Gy in 30% of the bladder volume may reduce the risk for late urinary complications. (Source: Radiologia Brasileira)
