X-ray Production, Tubes, and Generators X-rays are produced when highly energetic electrons interact with matter, converting some or all of their kinetic energy into electromagnetic radiation. The x-ray tube insert…
Interaction of Radiation with Matter This chapter introduces the concepts and principles that govern x- and γ-ray photon interactions with matter and the energetic electrons those interactions set into motion….
Medical Imaging Informatics In healthcare, medical informatics represents the process of collecting, analyzing, storing, and communicating information (data) that is crucial to the provision and delivery of appropriate patient care…
Radiation and the Atom Radiation simply refers to energy that propagates through space or matter. Two categories of radiation of importance in medical imaging are electromagnetic radiation (EMR) and sub-atomic…
Introduction to Medical Imaging Radiological imaging of the intact human body requires some form of energy to enter the body, interact, and then deliver a signal to a detector, typically…
The high soft tissue contrast and tissue characterization properties of magnetic resonance imaging allow further characterization of indeterminate mediastinal lesions on chest radiography and computed tomography, increasing diagnostic specificity, preventing…
Chest computed tomography (CT) is the modality of choice for mediastinal imaging. The high-resolution images provided by multi-detector CT result in routine visualization of normal anatomic structures, which can be…
Optimal assessment of the mediastinal masses is performed by a combination of clinical, radiological and often histological assessments. Image-guided transthoracic biopsy of mediastinal lesions is a minimally invasive and reliable…
The visceral mediastinum contains important vascular and non-vascular structures including the heart, great vessels, lymph nodes, and portions of the esophagus and trachea. Multiple imaging modalities, including chest radiography, computed…
Esophageal cancer is an uncommon malignancy that ranks sixth in terms of mortality worldwide. Squamous cell carcinoma is the predominant histologic subtype worldwide whereas adenocarcinoma represents the majority of cases…
