High-spatial-resolution Ultrasonography (USG), however, may be an alternative imaging modality in patients with occult scaphoid fractures. Technical improvements in sonography have led to higher spatial resolution of this diagnostic tool, and, thus, high-spatialresolutionUS may depict subtle post-traumatic changes of the cortex and/or periosteum, which may already be present immediately after the injury but which are not depicted on conventional radiographs. Furthermore, high-spatial-resolution US, compared with MR imaging, is more readily accessible, less time-consuming, and considerably less expensive. Radiography is the use of x-rays to visualize the internal structures of a patient. X-Rays are a form of electromagnetic radiation, produced by an x-ray tube. The x-rays are passed through the body and captured behind the patient by a detector; film sensitive to x-rays or a digital detector. There is variance in absorption of the x-rays by different tissues within the body, dense bone absorbs more radiation, while soft tissue allows more to pass through. This variance produces contrast within the image to give a 2D representation of all the structures within the patient. Hence present study was planned for comparative evaluation of ultrasonography and conventional radiography techniques for recognition of bone fractures in adult patients. The present study was planned in Department of Radio- Diagnosis, Lord Buddha Koshi Medical College & Hospital, Saharsa, Bihar. Total 25 cases of bony fractures referred to our hospital were evaluated in the present study. All the patients had undergone the USG and conventional radiography. The results of radiography and ultrasonography were compared to see their relative efficacy in the detection of fractures. Ultrasonography is a very rapid, cost-effective, and radiation free imaging technique for detection of superficially situated bone fractures. USG can replace conventional radiography in cases of isolated uncomplicated fractures. In cases of doubtful fracture, combination of USG and conventional plain films may be considered to avoid unnecessary exposures from higher imaging like CT scan. It can be considered as the imaging of choice when CT or conventional radiography are not advised as in pregnant women.
