Abstract

Resumen: Este artículo explora el papel de la tomografía computarizada de alta resolución (TCAR) en el diagnóstico de las enfermedades pulmonares intersticiales difusas (EPID), discutiendo los hallazgos tomográficos claves, las alteraciones parenquimatosas y la importancia de identificar diversos patrones radiológicos, con un enfoque especial en el patrón de neumonía intersticial usual (UIP, por sus siglas en inglés). Ante la complejidad y diversidad de manifestaciones de las enfermedades pulmonares intersticiales difusas (EPID), es esencial la evaluación colaborativa de un equipo multidisciplinario, en el que el radiólogo desempeña un papel fundamental en la cadena diagnóstica mediante la TCAR. Este exámen permite la detección de las alteraciones parenquimatosas en las EPID, tales como opacidades en vidrio esmerilado, consolidación, patrones reticulares, bronquiectasias/bronquioloectasias por tracción y panalización. La interpretación y asociación de estos hallazgos, junto con su distribución, facilita el establecimiento de patrones radiológicos específicos que, además de indicar posibles etiologías, orientan las opciones terapéuticas más adecuadas. La adopción de protocolos de imagen específicos y el uso de un lenguaje estandarizado son esenciales para aumentar la precisión diagnóstica. Además, la incorporación de innovaciones tecnológicas, como la avanzada tecnología de conteo de fotones y el análisis automatizado mediante inteligencia artificial, prometen mejorar significativamente la identificación y cuantificación de las alteraciones intersticiales, configurando el futuro de la radiología torácica. Abstract: This article explores the role of high-resolution computed tomography (HRCT) in the diagnosis of diffuse interstitial lung diseases (ILD), discussing key tomographic findings, parenchymal changes, and the importance of identifying various radiological patterns, with a special focus on the usual interstitial pneumonia (UIP) pattern. Given the complexity and diversity of manifestations of diffuse ILD, the collaborative evaluation of a multidisciplinary team, in which the radiologist plays a fundamental role in the diagnostic chain using HRCT, is essential. This exam enables the detection of parenchymal alterations in DILD, such as ground-glass opacities, consolidation, reticular patterns, traction bronchiectasis/bronchiectasis, and honeycombing. The interpretation and association of these findings, along with their distribution, facilitate the establishment of specific radiological patterns that, in addition to indicating possible etiologies, guide the most appropriate therapeutic options. The adoption of specific imaging protocols and the use of standardized language are essential to increase diagnostic accuracy. Moreover, the incorporation of technological innovations, such as advanced photon counting technology and automated analysis through artificial intelligence, promise to significantly improve the identification and quantification of interstitial alterations, shaping the future of thoracic radiology.

Abstract

Background: PET/CT (Positron Emission Tomography/Computed Tomography) is widely used in nodal and metastatic staging of lung cancer patients. Aim: To analyze PET/CT detection of metastatic disease in patients with lung cancer. Material and Methods: We reviewed retrospectively F18Fluorodeoxyglucose PET/CT scans performed between December 2008 and December 2013. We selected 143 patients aged 30 to 92 years (63% males) with confirmed lung cancer referred for staging, with no previous treatment. We reviewed whole body PET/CT and brain magnetic resonance images. SUVmax (Standardized Uptake Value maximum) of primary pulmonary lesion, hilar/mediastinal nodes, and distant metastases were calculated. Results: Histological types encountered were adenocarcinoma in 55%, squamous-cell in 15%, small-cell in 8%, large-cell in 6% and adeno-squamous in 2%. In 22 cases (15%) histology was not available. Nodal involvement was observed in 60% of patients (44% hilar and 48% mediastinal). Skip metastases (mediastinal involvement without hilum involvement) were encountered in 17% of cases, and were significantly more common among high uptake lung tumors (p < 0.01). Best SUVmax cut-off for node involvement was 4.4 for hilum and 4.0 for mediastinum (sensibility: 86.4%, specificity: 99.8%). Sixty six patients (46.2%) showed distant metastases on PET/CT. The most common metastases were osseous in 22%, adrenal in 16%, hepatic in14%, pulmonary in 14% and cerebral in 12%. PET/CT detected a second unexpected synchronic cancer in eight patients (6%). Conclusions: PET/CT is accurate for nodal staging using an uptake index as SUVmax. Distant metastases are common, especially in bone, adrenal glands and liver.
