Core Radiology is, I believe, a better foundational book than B&H awesome for basic neuroanatomy), FreitasRad's Musculoskeletal MRI. e-Anatomy is an award-winning interactive atlas of human anatomy. It is the most complete reference of human anatomy available on web, iPad, iPhone and. Practical Radiological Anatomy is an illustrated and concise revision textbook for radiology trainees learning to interpret all modes of imaging.
It does so by an initial traditional anatomical description of each organ or system followed by the radiological anatomy of that part of the body using all the relevant imaging modalities. The third edition addresses the anatomy of new imaging techniques including three-dimensional CT, cardiac CT, and CT and MR angiography as well as the anatomy of therapeutic interventional radiological techniques guided by fluoroscopy, ultrasound, CT and MR.
The text has been completely revised and over new images, including some in colour, have been added.
The book is primarily aimed at those training in radiology, but will be of use to all radiologists and radiographers both in training and in practice, and to medical students, physicians and surgeons and all who use imaging as a vital part of patient care.
The third edition brings the basics of radiological anatomy to a new generation of radiologists in an ever-changing world of imaging.

Color-flow Doppler ultrasound measures the severity of peripheral vascular disease and is used by cardiologists for dynamic evaluation of the heart, heart valves and major vessels. Stenosis , for example, of the carotid arteries may be a warning sign for an impending stroke.
A clot , embedded deep in one of the inner veins of the legs, can be found via ultrasound before it dislodges and travels to the lungs, resulting in a potentially fatal pulmonary embolism. Ultrasounds is useful as a guide to performing biopsies to minimise damage to surrounding tissues and in drainages such as thoracentesis.
Small, portable ultrasound devices now replace peritoneal lavage in trauma wards by non-invasively assessing for the presence of internal bleeding and any internal organ damage. Extensive internal bleeding or injury to the major organs may require surgery and repair. MRI uses strong magnetic fields to align atomic nuclei usually hydrogen protons within body tissues, then uses a radio signal to disturb the axis of rotation of these nuclei and observes the radio frequency signal generated as the nuclei return to their baseline states.
An advantage of MRI is its ability to produce images in axial , coronal , sagittal and multiple oblique planes with equal ease. MRI scans give the best soft tissue contrast of all the imaging modalities. With advances in scanning speed and spatial resolution, and improvements in computer 3D algorithms and hardware, MRI has become an important tool in musculoskeletal radiology and neuroradiology.
One disadvantage is the patient has to hold still for long periods of time in a noisy, cramped space while the imaging is performed. Recent improvements in magnet design including stronger magnetic fields 3 teslas , shortening exam times, wider, shorter magnet bores and more open magnet designs, have brought some relief for claustrophobic patients.
However, for magnets with equivalent field strengths, there is often a trade-off between image quality and open design.
MRI has great benefit in imaging the brain, spine, and musculoskeletal system. The use of MRI is currently contraindicated for patients with pacemakers, cochlear implants, some indwelling medication pumps, certain types of cerebral aneurysm clips, metal fragments in the eyes and some metallic hardware due to the powerful magnetic fields and strong fluctuating radio signals to which the body is exposed.
Main article: Nuclear medicine Nuclear medicine imaging involves the administration into the patient of radiopharmaceuticals consisting of substances with affinity for certain body tissues labeled with radioactive tracer.
The most commonly used tracers are technetiumm, iodine, iodine, gallium, indium, thallium and fludeoxyglucose 18F 18F-FDG. The heart , lungs , thyroid , liver , brain , gallbladder , and bones are commonly evaluated for particular conditions using these techniques.
While anatomical detail is limited in these studies, nuclear medicine is useful in displaying physiological function. The excretory function of the kidneys, iodine-concentrating ability of the thyroid, blood flow to heart muscle, etc.
The principal imaging devices are the gamma camera and the PET Scanner, which detect the radiation emitted by the tracer in the body and display it as an image.
With computer processing, the information can be displayed as axial, coronal and sagittal images single-photon emission computed tomography - SPECT or Positron-emission tomography - PET. In the most modern devices, nuclear medicine images can be fused with a CT scan taken quasisimultaneously, so the physiological information can be overlaid or coregistered with the anatomical structures to improve diagnostic accuracy. Positron emission tomography PET scanning deals with positrons instead of gamma rays detected by gamma cameras.
The positrons annihilate to produce two opposite traveling gamma rays to be detected coincidentally, thus improving resolution. In PET scanning, a radioactive, biologically active substance, most often 18F-FDG, is injected into a patient and the radiation emitted by the patient is detected to produce multiplanar images of the body.
Metabolically more active tissues, such as cancer, concentrate the active substance more than normal tissues. PET images can be combined or "fused" with anatomic CT imaging, to more accurately localize PET findings and thereby improve diagnostic accuracy.
The technology recently blossomed after passing the technical hurdle of altered positron movement in strong magnetic field thus affecting the resolution of PET images and attenuation correction. Main article: Interventional radiology Interventional radiology IR or sometimes VIR for vascular and interventional radiology is a subspecialty of radiology in which minimally invasive procedures are performed using image guidance. Some of these procedures are done for purely diagnostic purposes e.
Minimally invasive procedures are currently performed more than ever before. These procedures are often performed with the patient fully awake, with little or no sedation required.
Interventional Radiologists and Interventional Radiographers  diagnose and treat several disorders, including peripheral vascular disease , renal artery stenosis , inferior vena cava filter placement, gastrostomy tube placements, biliary stents and hepatic interventions. Images are used for guidance, and the primary instruments used during the procedure are needles and catheters. The images provide maps that allow the Clinician to guide these instruments through the body to the areas containing disease.
By minimizing the physical trauma to the patient, peripheral interventions can reduce infection rates and recovery times, as well as hospital stays. To be a trained interventionalist in the United States, an individual completes a five-year residency in radiology and a one- or two-year fellowship in IR. San Diego, CA, Main article: Teleradiology Teleradiology is the transmission of radiographic images from one location to another for interpretation by an appropriately trained professional, usually a Radiologist or Reporting Radiographer.
It is most often used to allow rapid interpretation of emergency room, ICU and other emergent examinations after hours of usual operation, at night and on weekends. In these cases, the images can be sent across time zones e. However at present, large private teleradiology companies in the U.
Teleradiology can also be used to obtain consultation with an expert or subspecialist about a complicated or puzzling case. In the U. Teleradiology requires a sending station, a high-speed internet connection, and a high-quality receiving station.
At the transmission station, plain radiographs are passed through a digitizing machine before transmission, while CT, MRI, ultrasound and nuclear medicine scans can be sent directly, as they are already digital data.
The computer at the receiving end will need to have a high-quality display screen that has been tested and cleared for clinical purposes. Reports are then transmitted to the requesting clinician. The major advantage of teleradiology is the ability to use different time zones to provide real-time emergency radiology services around-the-clock. The disadvantages include higher costs, limited contact between the referrer and the reporting Clinician, and the inability to cover for procedures requiring an onsite reporting Clinician.
Laws and regulations concerning the use of teleradiology vary among the states, with some requiring a license to practice medicine in the state sending the radiologic exam. Lastly, the major benefit of teleradiology is that it can be automated with modern machine learning techniques   . X-ray of a hand with calculation of bone age analysis United States[ edit ] Radiology is an expanding field in medicine that has expanded rapidly after due to advances in computer technology, which is closely linked to modern imaging techniques.
Applying for residency positions in radiology is relatively competitive.
Applicants are often near the top of their medical school classes, with high USMLE board examination scores. Diagnostic radiologists must complete prerequisite undergraduate education, four years of medical school to earn a medical degree D. The American Board of Radiology ABR administers professional certification in Diagnostic Radiology, Radiation Oncology and Medical Physics as well as subspecialty certification in neuroradiology, nuclear radiology, pediatric radiology and vascular and interventional radiology.
The Core Exam is given after 36 months of residency. This computer-based examination is given twice a year in Chicago and Tucson. It encompasses 18 categories.
A pass of all 18 is a pass. A fail on 1 to 5 categories is a Conditioned exam and the resident will need to retake and pass the failed categories. A fail on over 5 categories is a failed exam. The Certification Exam, can be taken 15 months after completion of the Radiology residency.
This computer-based examination consists of 5 modules and graded pass-fail.
