HIGADO GRASO: ULTRASONIDO Y CORRELACION ANATOMOPATOLOGICA
Csendes G,Paula; Paolinelli G,Paola; Busel M,David; Venturelli A,Verónica; Rodríguez,Jorge;
Revista chilena de radiología , 2004, DOI: 10.4067/S0717-93082004000200003
Abstract: abstract: fatty liver is a pathology characterized for accumulation of triglycerides within the hepatocytes. today is diagnosed frequently by ultrasound and is important to know the ultrasonographic findings for the diagnosis. our purpose was to correlate ultrasound and pathologic findings in the diagnosis of steatosis and propose grades of severity. this study demonstrated moderate concor-dance between ultrasound and biopsy findings
HIGADO GRASO: ULTRASONIDO Y CORRELACION ANATOMOPATOLOGICA

Revista Chilena de Radiología , 2004,
Abstract: : El hígado graso es una entidad patológica que se caracteriza por acumulación de glóbulos de grasa dentro de los hepatocitos. Es una patología que en ultrasonido se diagnostica cada vez más, sin embargo es necesario usar algunos criterios para su diagnóstico. Nuestro objetivo fue estandarizar criterios ultrasonográficos, correlacionándolos con anatomía patológica, para diagnóstico de esteatosis y su cuantificación en grados de severidad (leve, moderado, severo). Este estudio mostró una concordancia moderada entre el ultrasonido y biopsia Abstract: Fatty liver is a pathology characterized for accumulation of triglycerides within the hepatocytes.

ULTRASONIDO DOPPLER DE EXTREMIDADES INFERIORES PARA EL ESTUDIO DE LA INSUFICIENCIA VENOSA
Paolinelli G,Paola;
Revista chilena de radiología , 2009, DOI: 10.4067/S0717-93082009000500005
Abstract: venous insufficiency is defined as an impaired venous return, which affects the superficial, or the deep system, or both. this condition may be caused either by an alteration in the muscle pump, a venous obstruction, a valvular incompetence or right-sided heart failure. it translates into a dynamic venous hypertension manifested through the development of varicose veins or trophic skin changes. the surface failure is due to the presence of veno-venous shunts that provoke a flow loss from the deep system through a vanishing point and then returns through another entry point. the study is performed with the patient in standing position, stimulating muscle pump through various exercises or increasing central pressure with valsalva maneuver. the mapping is a graphic expression of the study, and it must show the type of shunt, location and pattern of varicose veins.
ULTRASONIDO DOPPLER DE EXTREMIDADES INFERIORES PARA EL ESTUDIO DE LA INSUFICIENCIA VENOSA LOWER LIMB DOPPLER ULTRASOUND FOR THE STUDY OF VENOUS INSUFFICIENCY
Paola Paolinelli G
Revista Chilena de Radiología , 2009,
Abstract: La insuficiencia venosa se define como una alteración en el retorno venoso, que compromete el sistema superficial, profundo o ambos, cuya causa puede ser alteración en la bomba muscular, obstrucción venosa, incompetencia valvular o falla cardíaca derecha. Se traduce en una hipertensión venosa dinámica que se manifiesta a través del desarrollo de várices, o cambios tróficos de la piel. La insuficiencia superficial se debe a la presencia de shunts veno-venosos, que consisten en cortocircuitos en que se pierde flujo desde el sistema profundo a través de un punto de fuga y luego regresa por otro punto de entrada. El estudio se realiza de pie, estimulando la bomba muscular a través de distintas maniobras o aumentando la presión central con Valsalva. Elmapeo es la expresión gráfica del estudio, y debe demostrar el tipo de shunt, localización y patrón varicoso.

INESTABILIDAD GLENOHUMERAL: LO QUE EL RADIOLOGO DEBE SABER
Zamorano C,Carolina; Mu?oz Ch,Sara; Paolinelli G,Paola;
Revista chilena de radiología , 2009, DOI: 10.4067/S0717-93082009000300006
Abstract: glenohumeral instability is a common cause of pain and functional limitation of the shoulder, which involves symptomatic subluxation or dislocation of the humeral head with respect to the glenoid fossa. glenohumeral instability may be classified according to several parameters: degree, direction, timing, etiology and biomechanics of the dislocation, among others. imaging methods play an important role in the evaluation of glenohumeral instability, being all of them useful, complementary, and not necessarily mutually exclusive modalities. the following article presents a review of the main types of glenohumeral instability and related imaging findings.
INESTABILIDAD GLENOHUMERAL: LO QUE EL RADIOLOGO DEBE SABER GLENOHUMERAL INSTABILITY: WHAT THE RADIOLOGIST SHOULD KNOW
Carolina Zamorano C,Sara Mu?oz Ch,Paola Paolinelli G
Revista Chilena de Radiología , 2009,
Abstract: La inestabilidad glenohumeral es una causa frecuente de dolor y limitación funcional del hombro, que implica subluxación o luxación sintomática de la cabeza humeral con respecto de la fosa glenoidea. Puede clasificarse considerando varios aspectos: grado, dirección, cronología, etiología y biomecánica de la luxación, entre otros. La imaginología juega un rol importante en la evaluación de la inestabilidad glenohumeral, siendo todos los métodos de imágenes útiles, complementarios entre sí y no necesariamente excluyentes. En el siguiente artículo presentamos una revisión de los principales tipos de inestabilidad glenohumeral y los hallazgos imaginológicos asociados.
