Q. Which of these is not a plain radiographic technique or radiographic view?
a. Stress view
b. Traction view
c. Subtraction view
d. Weight bearing view
Answer -
c
Stress views are taken with putting external forces over desired anatomical reason to recreate position of pathological laxity due to any reason. eg. stress view of ankle or knee to demonstrate ligamentous injury etc
Traction views are done to clarify images in radiographs to show better anatomical details eg. comminuted fractures if seen in normal radiograph don't clearly show fracture details like number and pattern of fracture fragments etc. Traction given to extremity disengages fragments and is helps evaluate fracture pattern better. The only caveat is that it is painful in acute traum settings and may require anaesthesia at times.
Weight bearing views are done in weight bearing structures to simulate loading posture and clearfies things in some disorders eg. weight bearing radiographs for knee, ankle or foot regions.
Subtraction imaging is great tool to know details that conventional overlap of structures hide. digital subtraction helps us look into those sites such as inside joint or behind a complex bony anatomy. This process is not possible in plain radiography and requires advance imaging like CT scan.
