The chest x-ray is the most frequently requested radiologic examination.In fact every radiologst should be an expert in chest film reading.The interpretation of a chest film requires the understanding of basic principles.
Our medical student radiology curriculum provides links to investigations and core pathology that medical students will encounter in their training as well as pathologies that are expected to be diagnosed on initial imaging come graduation.
If all of the x-rays continue through (e.g. air), that area of the image has little density and is black. If the x-rays are blocked (e.g. bones), that area of the image is very dense and is therefore white. There are five basic densities you should be able to recognize - the differences between them can be subtle and require experience! Try to identify each of the five densities on the attached chest x-ray:
CT, radiography, and fluoroscopy all work on the same basic principle: an X-ray beam is passed through the body where a portion of the X-rays are either absorbed or scattered by the internal structures, and the remaining X-ray pattern is transmitted to a detector (e.g., film or a computer screen) for recording or further processing by a computer. These exams differ in their purpose:
The training for these basic IR procedures is not uniform. However, considering the importance of these interventions, it is imperative for all radiologists to have an understanding of these procedures for better patient care. In this review we aim to provide practice essentials for basic IR procedures. These details may be of help for radiologists-in-training as well as radiologists practicing IR.

This course by Dr. Robert Boyles, PT, DSc, OCS, FAAOMPT, covers basic principles and interpretation of diagnostic imaging modalities as they apply for all healthcare providers with imaging privileges. The emphasis is on plain film radiography, including basic physics of the imaging technique, viewing and interpreting films, radiographic anatomy, and clinical correlation with patient cases. Other types of imaging, including contrast films, magnetic resonance imaging, and computed tomography will also be introduced.
Covers the history of radiology and gives the student the basics of radiographic image production. Students will be introduced to the viewing and interpretation of plain orthopaedic radiographs, MRIs, and other types of permanent imaging relating to orthopaedics and terminology relating directly to the skeletal system and fracture healing and describing a fracture as it relates to the radiographic image.
Diagnostic radiology helps health care providers see structures inside your body. Doctors that specialize in the interpretation of these images are called diagnostic radiologists. Using the diagnostic images, the radiologist or other physicians can often:
Although the applications of DECT described in this article demonstrate exciting capabilities, the current clinical techniques only scratch the surface of the potential for material separation. Ongoing areas of active clinical research in abdominal imaging include detection and stratification of liver steatosis and fibrosis.24 Material separation techniques can be used as a tool for electronic cleansing of the colon on CT colonography by differentiating tagged fecal materials from luminal air and air-tagging mixtures.25 In musculoskeletal imaging, uric acid material decomposition images can help identify articular deposition of uric acid crystals (in addition to detection of uric acid renal stones). Material separation can also help detect bone marrow edema on CT to evaluate for subtle fractures in the setting of trauma or possible pathologic fracture. In neuroradiology, iodine images can be used to distinguish intracerebral hemorrhage from contrast after reperfusion therapy for acute ischemic stroke.26 Finally, material separation through DECT may allow for development of new intravenous and oral contrast media as well as quantification of additional materials like gold, iron, copper, and zinc.
The Medical Assistant Technician with Emphasis in Basic X-Ray Diploma program prepares the student to acquire the necessary skills to perform under the supervision of a physician providing medical office administrative services, clinical duties including patient intake and care, routine diagnostic, and basic x-ray procedures in the classroom and a supervised clinical practice or capstone. Graduates will be eligible for Basic Machine Operator licensure. Graduates will be eligible for Basic Machine Operator licensure.
In this medical assistant course, Florida Technical College students will examine the anatomy and physiology of the human body and the relationship with the medical terms and abbreviations used to designate them. They will discuss the levels of human body organization, gynecologic conditions, reproductive, circulatory, sensory, and lymphatic systems, and an overview of the brain function. Furthermore, they will analyze the meaning of medical terms and procedures through their basic components such as prefixes, suffixes, and roots, in addition to special numerical, positional and condition.
In this medical assistant course, students will analyze the basic rules of preparation and administration of oral and parenteral medications. They will examine the parts of a prescription as well as commonly prescribed medications, how they affect the body, and why they are prescribed. They will demonstrate preparation and administration of medications using various techniques, including intramuscular, subcutaneous, intradermal, and Z-track injections. In addition, they will evaluate the Occupational Safety and Health Administration (OSHA) guidelines in preparation for the OSHA bloodborne pathogen certification.
In this medical assistant course, students will analyze commonly-performed cardiovascular and pulmonary function studies. They will identify life threatening signs of arrhythmia, as well as daily functions and responsibilities of a medical assistant technician. In addition, they will also perform cardiorespiratory procedures such as a 12-lead electrocardiogram without artifacts as well as first aid and basic life-support procedures. They will practice acquired skills by completing lab exercises in preparation for the certification test.
Radiology (/ˌreɪdɪˈɒlədʒi/ rey-dee-ol-uh-jee) is the medical discipline that uses medical imaging to diagnose diseases and guide their treatment, within the bodies of humans and other animals. It began with radiography (which is why its name has a root referring to radiation), but today it includes all imaging modalities, including those that use no electromagnetic radiation (such as ultrasonography and magnetic resonance imaging), as well as others that do, such as computed tomography (CT), fluoroscopy, and nuclear medicine including positron emission tomography (PET). Interventional radiology is the performance of usually minimally invasive medical procedures with the guidance of imaging technologies such as those mentioned above.
The modern practice of radiology involves several different healthcare professions working as a team. The radiologist is a medical doctor who has completed the appropriate post-graduate training and interprets medical images, communicates these findings to other physicians by means of a report or verbally, and uses imaging to perform minimally invasive medical procedures. The nurse is involved in the care of patients before and after imaging or procedures, including administration of medications, monitoring of vital signs and monitoring of sedated patients. The radiographer, also known as a "radiologic technologist" in some countries such as the United States and Canada, is a specially trained healthcare professional that uses sophisticated technology and positioning techniques to produce medical images for the radiologist to interpret. Depending on the individual's training and country of practice, the radiographer may specialize in one of the above-mentioned imaging modalities or have expanded roles in image reporting.
Plain radiography was the only imaging modality available during the first 50 years of radiology. Due to its availability, speed, and lower costs compared to other modalities, radiography is often the first-line test of choice in radiologic diagnosis. Also despite the large amount of data in CT scans, MR scans and other digital-based imaging, there are many disease entities in which the classic diagnosis is obtained by plain radiographs. Examples include various types of arthritis and pneumonia, bone tumors (especially benign bone tumors), fractures, congenital skeletal anomalies, and certain kidney stones. 041b061a72
