Arteritis de células gigantes: compromiso extenso de la aorta y grandes ramas demostrado por tomografía por emisión de positrones. Caso clínico
(Sociedad Medica de Santiago, 2016)
Large vessel vasculitis and particularly Temporal Arteritis are systemic diseases
that may affect the aorta and its major branches, mainly involving extra
cranial branches of the carotid artery. We report a 72-year-old ...

Infección por Bartonella henselae: utilidad de las imágenes en el diagnóstico y seguimiento.
(Sociedad Chilena de Infectología, 2017)
Bartonella henselae infection is a frequent zoonosis from the domestic cat. It is presented with regional lymphadenitis in the majority of cases. Searching and characterization of lymph nodes by diagnostic imaging can be ...

PET Reconstruction With Non-Negativity Constraint in Projection Space: Optimization Through Hypo-Convergence
(IEEE, 2020)
Standard positron emission tomography (PET) reconstruction techniques are based on maximum-likelihood (ML) optimization methods, such as the maximum-likelihood expectation-maximization (MLEM) algorithm and its variations. ...
Quantitative comparison between single-photon emission computed tomography and positron emission tomography imaging of lung ventilation with 99mTc-technegas and 68Ga‑gallgas in patients with chronic obstructive pulmonary disease: a pilot study
(Wolters Kluwer - Medknow, 2019)
The aim of this study was quantitative comparison between 68Ga‑Gallgas positron emission tomography (PET) and 99mTc‑Technegas single photon emission computed tomography (SPECT) for lung ventilation function assessment in ...
Inter-hemispheric asymmetry of nigrostriatal dopaminergic lesion: A possible compensatory mechanism in Parkinson's disease
(2011)
The onset of Parkinson’s disease (PD) is characterized by focal motor features in one body part, which are usually correlated with greater dopaminergic depletion in the contralateral posterior putamen. The role of dopamine ...
Needle fracture during endobronchial ultrasound-guided transbronchial needle aspiration
(American Thoracic Society, 2016)
A 57-year-old man with new-onset hoarseness and markedly enlarged left paratracheal lymphadenopathy underwent an endobronchial ultrasound–guided transbronchial needle aspiration (EBUS-TBNA) that revealed non–small cell ...
