The effectiveness of screening programs is proved by an increase in detection rate of HCC <2 cm (from <5% in the 90s in Europe to > 30% today in Japan) with curative therapy options. The main problem of ultrasound screening is that, in order to be cost-effective, it should be applied to the general population and not in tertiary hospitals.
Peritoneal inclusion cysts are commonly visualized on ultrasonography as a spider-web-like pattern. A normal-looking ovary is encircled by a big, irregular or oval, echolucent cyst with fine internal septations. The ovary is frequently located in the middle of the inclusion cyst or on its lateral aspect, appearing to be dangling inside the cyst ...
The diagnosis of pancreatic MCN is typically achieved with imaging. If the results of imaging (CT/MRI) are unclear, then endoscopic ultrasound with fine needle aspiration (EUS-FNA) of the cyst may be necessary. [1] Cyst fluid analysis may help distinguish potentially premalignant mucinous cysts (MCNs and IPMNs), from benign non-mucinous cysts. [1]
Breast ultrasound is considered the best option when diagnosing breast cysts because it is 95 to 100% accurate, it provides a clear image on the cyst's appearance (simple or complex) and it may also distinguish between solid lumps and fluid-filled cysts, which a mammogram cannot do. [7]
The incidence increases with age, as at least 50% of people above the age of 50 have a simple cyst in one of the kidneys. Cysts cause posterior enhancement as a consequence of reduced attenuation of the ultrasound within the cyst fluid (Figure 5). The simple cyst is a benign lesion, which does not require further evaluation. [1]
Ultrasound Imaging vs. Ultrasound Therapy. One of the many advantages of SDT compared to PDT is the ability of SDT to penetrate deeply placed solid tumors allowing a wider treatment range. [1] Despite this fact, there are limitations to SDT that must be overcome or have optimized components in order to expand the effect and application of SDT. [31]
Epididymal cyst is a harmless sac in the testicles filled with fluid. [2] The most frequent clinical presentation occurs when a routine physical examination yields an unexpected finding, which is then confirmed by scrotal ultrasonography . [ 1 ]
The indications to do FNAC are: nodules more than 1 cm with two ultrasound criteria suggestive of malignancy, nodules of any size with extracapsular extension or lymph nodes enlargement with unknown source, any sizes of nodules with history of head and neck radiation, family history of thyroid carcinoma in two or more first degree relatives ...
