What is the aim of Radiology?
Radiology is the field of medicine that uses imaging techniques (such as X-rays) to diagnose and treat disease. It may be used diagnostically in order to determine if a medical condition is present or not (such as finding a lung cancer), interventionally as a procedure (such as removing a blood clot in an artery), or as a treatment. such as ...
What is interventional radiology?
As an alternative to surgery, interventional radiology may be used to control bleeding (hemorrhage) in conditions ranging from gastrointestinal bleeding, to postpartum bleed ing, to trauma. Bleeding may be controlled by blocking a blood vessel (as noted above), placing a stent, using a balloon to apply pressure, and more.
Why is radiology important?
With radiology procedures, it's important to weigh the risks and benefits of imaging and to consider possible alternatives when available . The different interventional procedures can also carry risks, and it's important to discuss these with your doctor.

What is the difference between a bone and an X-ray?
With X-rays, denser structures, such as bones, appear white (opaque) whereas air filled areas (such as the lungs) appear black. Most structures of the body are in shades of gray between these two. X-rays may be used alone to diagnose conditions such as fractures, some pneumonias, or a bowel obstruction.
Why is a syringe used as a diagnostic test?
It may be used diagnostically in order to determine if a medical condition is present or not (such as finding a lung cancer), interventionally as a procedure (such as removing a blood clot in an artery), or as a treatment. such as giving radiation therapy to treat cancer.
How does radiation therapy work?
In external beam radiotherapy, radiation is applied from outside of the body on a table resembling a CT machine. It may be used: 1 Before surgery (neoadjuvant radiation therapy) to reduce the size of a tumor 2 After surgery (adjuvant radiation therapy) to "clean up" any leftover cancer cells and reduce the risk of recurrence 3 As a palliative therapy to reduce pain (such as with bone metastases) or an obstruction due to a tumor
Is radiology a field?
Some people think of radiology as a field that's primarily limited to X-rays and CT scans, but the scope is much broader. Once primarily a method to diagnosis injuries and medical conditions, interventional radiology now provides alternatives to a number of previously more invasive procedures.
What is the most important diagnostic imaging tool in cardiology?
Echocardiography remains the most important diagnostic imaging tool in clinical cardiology practice. Since its development by Edler and Herz almost five decades ago, and routine clinical implementation a decade later, echocardiography has developed into an intuitive, comprehensible, and practical method for evaluating cardiac morphology and function rapidly and repeatedly.
Why is imaging important in cardiovascular disease?
Imaging is of paramount importance in assessment of cardiovascular disease. The diagnosis of disease has been revolutionized by the ability to gain high-resolution imaging of all aspects of the heart and vessels, and we are now able to visualize and assess function of everything ‘from the heart to the capillary’. As a result multiple modalities and approaches are used and the area has matured to a stage where it is not possible for everyone—or anyone—to have the same high level of specialist knowledge across all modalities. For the newcomer the range of options can appear confusing. Fortunately, some common approaches to cardiovascular imaging have developed that are transferable across modalities and allow anyone to pick up an image and begin to interpret what is seen. The basic things to get to grips with are the follwoing.
What is OCT imaging?
Like IVUS, optical coherence tomography (OCT) provides a crosssectional assessment of the coronary lumen and part of the vessel wall (Fig. 1.7). In the case of OCT the imaging modality used is reflected light. This provides a much higher resolution (10–20μm) image of the vessel wall than IVUS but with more limited penetration. In practical terms the OCT probe is integral to a wire which can be passed via a guide catheter into the coronary position of interest. Because red blood cells scatter light, prior to OCT imaging blood must be displaced by an optically clear medium such as an appropriate contrast or crystalloid. To image longer segments of coronary artery a proximal occlusion balloon may be inflated prior to blood dispacement and an automated pullback activated at ∼1mm/s with a frame rate of ∼15/s.
Why is aortography important?
Aortography is indicated for more precise assessment of the dimensions of the aortic root (particularly important in the surgical workup of aortic valve disease) and severity of aortic regurgitation (based on a qualitative assessment of the amount of contrast that passes back into the left ventricle) Aortography can also be used to identify the origin of coronary vessels or grafts.
What is the standard chest X-ray for cardiology?
The standard chest X-ray for cardiology investigation is based on the PA (postero-anterior) projection (Fig. 1.1), but in acute settings, with patients in bed, it may be recorded in AP (antero-posterior) format. Lateral views are not often additionally required unless further information on the lung lobes or position of pacing leads is considered necessary. Following the initial chest X-ray, the usual next step is likely to be a further imaging modality.
What is the imaging plane?

How do X-rays work?
An X-ray source and a detector then rotate around the patient, producing a narrow ‘fan-shaped’ beam of X-rays. These X-rays pass through sections of the patient’s body in order to create 'snapshots', which are then collated into one or multiple images of the internal organs and issues (FDA 2019).
