Although US of the lungs is increasingly used clinically, diagnostic radiologists are not routinely trained in its use and interpretation. Lung a highly sensitive specific modality that aids evaluation for many different abnormalities, including pneumonia, pleural effusion, pulmonary edema, pneumothorax. This review provides an overview lung to equip radiologist with knowledge needed interpret this modality. Supplemental material available article. © RSNA, 2021.
Sonoelastography is an ultrasound imaging technique where low amplitude, low-frequency shear waves (less than 0.1 mm displacement and less 1 kHz frequency) are propagated through internal organs, while real-time Doppler techniques used to image the resulting vibration pattern. When a discrete hard inhomogeneity, such as tumour, present within region of soft tissue, decrease in amplitude will occur at its location. This forms basis for tumour detection using sonoelastography. For...
A number of different approaches have been developed to estimate and image the elastic properties tissue. The biomechanical tissues are vitally linked function pathology, but cannot be directly assessed by conventional ultrasound, MRI, CT, or nuclear imaging. Research developments introduced new approaches, using either MRI ultrasound tissue response some stimulus. wide range stimuli has evaluated, including heat, water jets, vibration shear waves, compression, quasistatic single multiple...
Elastography is a technique that maps relative tissue stiffness. Ultrasonographic (US) elastography (sonoelastography) novel modality the subject of active research for clinical applications, primarily breast and prostate lesion imaging. Breast tumors generally have biomechanical properties different from those normal tissues: Tumors are usually stiffer. This phenomenon responsible contrast on elastograms. For gland breast, main image acquisition techniques vibration sonoelastography...
The shear wave velocity is one of a few important parameters that characterize the mechanical properties bio-materials. In this paper, two noninvasive methods are proposed to measure by inspecting interference patterns. method, sources placed on opposite sides sample, driven identical sinusoidal signals. waves from interact create patterns, which visualized vibration sonoelastography technique. spacing between pattern bands equals half wavelength. can be obtained taking product wavelength...
In this paper, we present needle insertion forces and motion trajectories measured during actual brachytherapy while implanting radioactive seeds in the prostate glands of 20 different patients. The was captured using ultrasound images a 6 degree-of-freedom electromagnetic-based position sensor. Needle velocity computed from information corresponding time stamps. From vivo data found maximum to be about 15.6 8.9 N for 17 gauge (1.47 mm) 18 (1.27 needles, respectively. Part difference is due...
To assess frequency and significance of enlarged nonpalpable supraclavicular lymph nodes by using chest computed tomography (CT) ultrasonography (US) in patients at initial diagnosis lung cancer.Fifty-five with no prior malignancy who presented suspected subsequently proven cancer any stage or a but potentially resectable were prospectively selected after CT. Chest CT other radiologic findings reviewed tabulated. Standardized US technique was used to identify guide needle biopsy (> =0.5 cm...
