Enlargement of a lymph node of the neck may appear as a manifestation of a variety of diseases, such as specific or nonspecific inflammation of head and neck organs, metastases, and hemoblastoses. The principle ultrasound signs of lymph node differentiation are the size, shape, structure, and ...
These findings are consistent with the 2015 American Thyroid Association (ATA) Guidelines that neck US is an ideal imaging modality in pediatric patients for the surveillance of PTC local recurrence or lymph node metastases. 展开 关键词: Pediatric endocrinology Pediatrics Thyroglobulin Thyroid cancer ...
THI has better diagnostic accuracy for axillary lymph node evaluation. Limitations of harmonic imaging As harmonic imaging is due to higher frequency waves, the main limitation is penetration into deeper tissues. Higher frequency also leads to more shadowing and could potentially pose a dilemma in ...
Imaging of lymph node metastases in the neck can have two major indications: (1) prognosis and assisting with choice of treatment; (2) staging and detection of clinically occult metastases in different levels of the neck. Both indications are discussed. The role and limitations of US and US-...
CAUTION: Historically, Basic Protocol 1 has been used extensively for cervical lymph node sampling of the head and neck, while Alternate Protocol has been used extensively for sampling of the axillary lymph nodes. Consultation with radiologists should be undertaken before the application of either samp...
The absence of suspicious US features together with negative BRAF testing predicted PTC without extrathyroidal extension or lymph node metastasis (negative predictive value 88%). Conclusions: With routine preoperative cervical US and molecular testing, a trained radiologist or surgeon can improve the ...
Moreover, a common procedure for a needle biopsy is sampling of lymph node enlargement. The enlargement may be caused by various reasons, such as metastatic lesions, inflammatory processes, lymphomas and other causes that are related to proliferation of lymphoid tissue. As tonsils consist of ...
On examination, mucopus in the nasal cavities with postnasal drip was found with a 3 cm × 3 cm, movable, tender lymph node in the level II region of the right neck. The remainder of the examination was unremarkable. Neck US was arranged and showed matted nodes measuring up to 1.1 cm ...
We know that occult lateral cervical lymph node metastases are common. In 1971, Attie et al11 presented their experience with elective neck dissection for DTC. In 115 patients who underwent elective neck dissection, 69% had positive nodes. In their patients with positive nodes there were no recu...
In their research, they demonstrated that HIFU alone could induce locoregional and systemic immune responses such as upregulation of DAMPs, IL-2 and IFN-γ cytokine, and NK cells of splenic and lymph node, which could convert a “cold” tumor to a “hot” and immunogenic tumor. When HIFU ...
