Widened mediastinum CXR

PRACTICE GUIDELINES: EVALUATION OF THE WIDENED MEDIASTINUM OBJECTIVES: 1. Define the indications of pursuing an evaluation to rule out a thoracic aortic injury. 
2. Suggest possible diagnostic paradigms for the evaluation of thoracic aortic injury.

DEFINITIONS: Thoracic aortic injury: A disruption of the thoracic aorta from blunt deceleration trauma. This injury usually occurs at the ductus arteriosum which is just distal to the take-off of the left subclavian artery. Occasionally, the aorta may rupture in the ascending portion and at the takeoff of the major vessels. Widened mediastinum: Definition: A mediastinum measurement of ≥8 cm or >1/3rd the transthoracic distance at the level of the aortic knob on a supine AP film.

1. Initially assume that there is an aortic injury on every patient with a rapid deceleration mechanism of injury. 
2. Evaluate and treat the ABC’s. Obtain blood pressure in both arms.
3. Obtain a chest X-ray. 
Examine for a widened mediastinum (≥8 cm at level of aortic knob). The following signs are confirmatory of a possible aortic injury, but in themselves, do not suggest the need for further evaluation. 
a. Pleural cap. 
b. Depressed left mainstem bronchus. 
c. Trachea or esophagus deviated to right. 
d. First and second rib fracture. 
e. Obliterated aorto-pulmonary window.
4. Assess for symptomatic upper extremity BP differences (> 10 mmHg), pseudocoarctation syndrome or infrascapular murmur. These are also suggestive of aortic injury.
5. If the possibility of aortic injury is considered at any point in the resuscitation, avoid hypertension. Extremely high blood pressures should be treated with a short acting intravenous beta-blocker (e.g., labetalol or esmolol).
6. If a widened mediastinum is found and the patient can sit up, obtain an upright chest X-ray. The sitting position will decrease the possibility of spurious widening of the mediastinum due to the gravity effects on the heart (i.e. splays it apart) and magnification from the AP projection.
7. If the mediastinum is still widened or an upright film cannot be performed, obtain a chest CT angiogram with cuts through the aortic arch. If the CT scan shows no periaortic mediastinal blood, or dissection flap within the lumen of the aorta, then an aortic injury has been ruled out.
8. A thoracic angiogram should be obtained in the following circumstance:
a. The chest X-ray shows a widened mediastinum and a CT scan or TEE cannot be performed.
b. A chest CT scan shows blood in the mediastinum or an aortic disruption. The need for angiogram will be determined by the cardiothoracic surgeon or vascular surgeon.

Free Handbook Abdominal X-rays for Medical Students

Free handbook radiology, Abdominal X-rays for Medical Students.
Abdominal X-rays for Medical Students is a comprehensive resource offering guidance on reading, presenting and interpreting abdominal radiographs. Suitable for medical students, junior doctors, nurses and trainee radiographers, this brand new title is clearly illustrated using a unique colour overlay system to present the main pathologies and to highlight the abnormalities in abdomen x-rays.
Abdominal X-rays for Medical Students:
  • Covers the key knowledge and skills necessary for practical use
  • Provides an effective and memorable way to analyse and present abdominal radiographs - the unique 'ABCDE' system as developed by the authors
  • Presents each radiograph twice, side by side: the first as seen in the clinical setting, and the second with the pathology clearly highlighted
  • Includes self-assessment to test knowledge and presentation technique
With a systematic approach covering both the analysis of radiographs and next steps mirroring the clinical setting and context, Abdominal X-rays for Medical Students is a succinct and up-to-date overview of the principles and practice of this important topic.

Learn to scan ultrasound

Color Atlas of Ultrasound Anatomy 
Standard Sectional Planes for Abdominal Scanning
Ultrasound scanning yields a series of sectional images. The basis for interpreting
the examination is the individual sectional image. At first
sight, it is easy to be confused by the variable appearance of an ultrasound
scan of the same region in different patients. This has numerous
causes, including differences in density, body fat, age-related differences,
overlying gas, and artifacts. In most cases the apparent discrepancies
are not based on true anatomical differences. When a systematic
scanning routine is closely followed, series of sectional images can be
obtained in every patient with remarkable consistency. Even if the
images themselves vary, the anatomical relationships that are demonstrated
remain constant.

This apk focuses on hyperacute ischemic stroke, which we define operationally as that early period after stroke onset when a significant portion of threatened brain is potentially salvageable.
The time period this encompasses will depend on many factors; it may only be a few minutes in some individuals or greater than 12 hours in others. In most people, this hyperacute period will encompass less than 6 hours when intervention is usually most
The authors believe that patients with acute ischemic stroke can benefit most from the earliest possible definitive diagnosis and rapid, appropriate treatment. In the setting of hyperacute stroke, imaging plays a vital role in the assessment of patients.
The most recent advances in imaging can identify the precise location of the occluded vessel, estimate the age of the infarcted core, and estimate the area at risk or the ‘ischemic penumbra’. This APLICATION ANDROID FOR RADIOLOGY will cover these modern imaging modalities; advanced computed tomography and magnetic resonance methods are considered in detail. These two modalities are emphasized because of their widespread availability and the rapid development of their capacities in the diagnosis of stroke. Only brief mention is made of other modalities because they are less widely available and less commonly used in the evaluation of hyperacute stroke patients.

Hemangioma in vertebral body X-ray

Benign, slow-growing tumor composed of vascular channels. Usually asymptomatic and identified in middle-aged patients. The coarse vertical trabecular pattern may extend into the pedicles and laminae. Soft-tissue and intraspinal extension of the tumor or secondary hemorrhage can produce a paraspinal mass.

It is one of these lytic lesions that appeares in X-ray of vertebral body and shows demineralized and occasionally expanded vertebral body with characteristic multiple coarse linear striations running vertically.

 Hemangioma of a vertebral body. Multiple coarse, linear striations run vertically in the demineralized vertebral body.
