Ultrasound real‐time imaging in the differential diagnosis of periapical lesions

Abstract

Ultrasound real-time imaging is a technique that may help make a differential diagnosis between cysts and granulomas by revealing the nature of the content of a bony lesion. This technique may have further applications in the study of other lesions of the jaws.

Ultrasound evaluation of intra-osseous cavity: A preliminary study in pig mandibles

“…18 The possibility of examining the lesion's content is admittedly one of the advantages offered by ultrasound, both in soft and hard tissue examination. 1,2,4,5,9,14,19 The possibility of using Doppler for real-time evaluation of the degree of lesion vascularization is another differential feature of ultrasound as it allows alterations to be evaluated depending on their degree of activity/aggressiveness. 1,14 Moreover, Rajendran and Sundaresan 20 described that the use of ultrasound allows verifying whether the blood flow is arterial or venous.…”

“…solid or cystic), thus making ultrasound a remarkably versatile diagnostic imaging tool for diagnosis. 1 Ultrasound has been successfully used in dentistry and by several researchers who investigate its use for evaluation of temporomandibular joint, periodontal and periapical lesions, and mandibular fracture, [2][3][4][5][6][7] as well as its benefits compared to other imaging modalities. 7,8 Ultrasound has been shown to be an interesting alternative new tool over the last few years for diagnosis of intra-osseous lesions in jaws, overcoming the limitations of conventional radiography and computerized tomography (CT) due to its availability of real-time multiplanar images, absence of ionizing radiation and accurate analysis.…”

“…It can also differentiate between simple and complex cyst, and on nature of the content differentiate into solid and semi solid cysts. 2,4 • Simple cysts appears totally anechoic lesions with limited or without internal echoes, e.g. radicular cyst • Complex cysts appear with dense internal echoes or high echo, e.g.…”

“…The technique is easy to perform and may show the presence, exact size, shape, content and vascular supply of endodontic lesions in the bone (6). US was found to be a reliable diagnostic technique in the differential diagnosis of periapical lesions (granulomas versus cysts) with the aid of the echo picture (hyperechoic and hypoechoic) and through the use of the colour laser Doppler effect to provide evidence of vascularity within the lesion (47,49). However, the ability of US to assess the true nature and type (e.g.…”
