Frequency Ultrasound

The low back is the weight-bearing part of the human trunk and has a complex anatomy with a variety of lesions. The traditional diagnostic imaging methods include X-ray, CT, and magnetic resonance imaging (MRI). With the rapid development of ultrasound diagnostic instruments and diagnostic techniques, high-frequency ultrasonography plays a more important role in the diagnosis of musculoskeletal disorders by virtue of its advantages of being safe, noninvasive, inexpensive, repeatable in a short period of time, and real-time imaging, especially for the display of fine structures of soft tissues, which is superior to CT and MRI. In this paper, the puncture needle was punctured near the intervertebral foramen, anti-inflammatory analgesics were injected under ultrasound surveillance. The anti-inflammatory and analgesic drugs mainly consist of local anesthetics and glucocorticoids. Local anesthetics can immediately block the nociceptive transmission of the diseased nerve, improve muscle tension, and eliminate muscle spasm, and glucocorticoids can effectively eliminate edema and inflammation of the lumbar nerve root and its surrounding tissues. The results showed that high-frequency ultrasound, as a noninvasive imaging examination, can clearly display the structure and spatial hierarchy of the skin, superficial fascia, deep fascia, and muscles of the low back, can provide real-time dynamic bilateral contrast observation, which can be the preferred imaging examination method for soft tissue disorders of the low back, and can compensate with general X-ray, CT, and magnetic resonance imaging to provide richer clinical diagnosis and treatment. It can provide richer imaging information for clinical diagnosis and treatment.

Despite extensive research into new ways of imaging the breast x-ray mammography and breast ultrasound, supplemented where necessary by magnetic resonance imaging, remain the techniques used for the vast majority of breast imaging for screening and the assessment of symptomatic breast problems. Recent advances in these technologies mean that these three techniques are highly effective for both detecting disease and for confirming normality. X-ray based imaging of the breast has been around now for 100 years but it is only in the last 10 years or so that digital technology developments have allowed for major advances in the efficacy of this technique. Digital breast tomosynthesis is currently the most promising technology as it has the potential to both improve detection of breast cancer and greatly reduce the numbers of false positive events. Technological advances in grey scale high frequency ultrasound imaging mean that it is now universally used in both symptomatic diagnosis and breast screening. Newer ultrasound techniques such as 3D imaging, Doppler analyses and elastography add some additional value but so far none of these has achieved their hoped for additional potential. Magnetic resonance imaging is currently the most sensitive imaging technique for the detection and characterisation of breast disease, but its cost remains a barrier to its more widespread use. Nuclear medicine techniques have a role is special circumstances but are yet to show that they should be used in routine practice. There are a large number of potential alternative new imaging techniques for the breast, but, as yet, none of these have shown any significant benefits over the current techniques. Dedicated breast computed tomography has perhaps the best promise but clinically effective breast imaging at present remains in the application and refinement of recent developments in digital mammography, ultrasound and magnetic resonance imaging.

Objective To compare the radiological (X-ray) and magnetic resonance imaging (MRI) findings in the sacroiliac (SI) joints in patients with early spondylarthropathy (SpA). Methods Forty consecutive HLA B27 antigen positive patients with early SpA and inflammatory low back pain (LBP) were studied. Their SI joints were investigated by posterior anterior plain X-ray and MRI. Results The X-ray and MRI examinations gave similar results in the SI joints in 24 patients, whereas they differed in 16, this difference being significant (p = 0.007). In those 16 patients, in whom the findings differed, the X-ray findings were normal but MRI showed sacroiliitis which was bilateral in 13 and unilateral in 3 patients. The kappa coefficient between these investigations was 0.346, showing poor agreement. Conclusion These results indicate that MRI may considerably improve the diagnosis of sacroiliitis in HLA B27 antigen positive patients with early SpA and inflammatory LBP.
