EXAM QUALITY FINDINGS
EXAM
- Describe the exam and any details of how it was performed.
ie-AP portable chest x-ray done today in the ICU ie-Multiple sections from a CT exam of the abdomen available – IV contrast was administered.
Number of images
Single or multiple
Prior films for comparison ie-There is an upright PA and Lateral chest x-ray done yesterday for comparison.
EXAM -
QUALITY-
FINDINGS
( Inspiration, Position, Exposure )
Inspiration – Adequate or decreased .
Poor is not a good descriptive choice. Remember: The patient is sick, the technologist gets the best film possible, and you weren’t there.
EXAM-
QUALITY
FINDINGS
(Inspiration , Position, Exposure )
Position –
Satisfactory positioning or note rotation by clavicle position compared to the midline spinous process.
* If clavicles project higher than the ribs its lordotic angulation
* PA will have less magnification of the heart than an AP
* If it is a portable --it’s an AP
* If there is a lateral view --it’s a PA
* If you can’t tell---say FRONTAL
EXAM -
QUALITY
- FINDINGS
( Inspiration, Position, Exposure)
Adequate or satisfactory are good terms to use.
Penetrationis also a term used to describe exposure. This is assessment of overall whiteness or darkness of the image.
Underexposureimage is too white (not enough photons) This limits evaluation in retrocardiac region and can simulate
CHF or interstitial disease.
Overexposur eimage is too dark. This can limit evaluation in the periphery of lung field especially for nodules and pneumothorax. It can also simulate COPD.
EXAM - QUALITY-
FINDINGS
Depending on Attending physician’s preference:
Formal recitation of reading the chest x-ray or
Description of dominant positive findings
Some attendings prefer a specific format when reading a chest x-ray
Know: Formal or informal —Which is appropriate for the situation
You can obtain this info from observations of other students, interns and residents.
A good habit is to start by describing post –op changes, support catheters and devices.
*Note the distal location of the device / catheter
*** MALPOSITION OF LINES AND CATHETERS IS OFTEN OVER LOOKED
DUE TO PATHOLOGY ON THE IMAGE.
Terms for catheter / device description:
. examples…
… The ET tube is above the carina
… Central catheter enters on the left extending to the SVC
… Post-op changes from mediastinal surgery are seen
DESCRIPTIVE TERMS
FOR
NORMAL CHEST EXAMS
CHEST WALL There is no soft tissue abnormality / pathology.
SKELETAL - No traumatic or destructive lesions are seen.
(note-degenerative changes in spine)
HEART SIZE - The cardiac silhouette is within normal limits.
MEDIASTINIUM There is no mass or abnormality.
HILA - There is no hilar mass or suspicious adenopathy.
PULMONARY VASCULARITY Is not engorged.
LUNGS - Show symmetric ventilation without mass or consolidation.
PLEURA - Shows sharp costophrenic angles without effusion.

E
C ompare
• Is there change from a previous exam.
• State your interpretation of the significance of the findings .
•
Discuss diagnosis and differential
Example
I would be concerned about ___
I think this is____
I would have to consider____
•Start by stating the most likely first.
•Mention the most significant that would be considered with this history and exam.
•Think in terms of general pathologic topics.
Infection, Neoplasm, Cardiovascular, Trauma
A
What are you going to do?
• observe
• compare with old studies
• repeat / new studies
• interventions
• lab studies
• additional physical exam
Example: * Plan to discuss with radiology about performing a percutaneous biopsy.
* Check to see if there are other previous exams.
Make statements
—don’t ask questions---Watch tone of voice!
Think simple, cheap, and safe as first step.
Be as general as you have to be and as specific as you can be.
Best film is the previous film
Hazy, ill defined, cloudlike, fluffy-------air space disease
Linear, reticular,coarse,-----interstitial disease
? Nodule-----repeat chest with nipple markers
? Pleural effusion----Decubitus film
? Apical disease----Lordotic film
Portable film----Repeat in department asap
? Retrocardiac mass----barium study---hiatal hernia
Chest wall lesion----get rib detail film
? Pneumothorax---get expiration film
Trace tubes & lines with your finger if exact position is not clear, tip is where problems arise.
Et tubes go distal into Rt. mainstem often. Practice finding carina.
Rib height = 1cm--Vertebral body=3cm
If it is calcified, goes away or remains stable over time = benign
X-ray / CT---------------------------density
Ultrasound----------------------echogencity / anechoic
Nuclear medicine------------intensity / activity
MR------------------------------------- intensity / signal
