Article Synopsis
  • The study investigates how body measurements and ultrasound features affect the choice between fine-needle aspiration biopsy (FNAB) and fine-needle non-aspiration biopsy (FNNAB) for diagnosing thyroid nodules, aiming for better management and cancer detection.
  • A total of 188 cases with 225 nodules were analyzed, comparing the diagnostic effectiveness of FNAB and FNNAB based on criteria like nodule shape, size, vascularity, and patient obesity.
  • Results showed that FNAB had a higher diagnostic success rate than FNNAB, especially in specific nodule characteristics and certain patient demographics, indicating its superiority in various clinical situations.

Objective: Endobronchial ultrasound-guided transbronchial needle aspiration has been successfully applied in both diagnosis and staging of mediastinal and hilar lymphadenopathies and masses, especially in malignant cases. However, the optimal procedure of Endobronchial ultrasound-guided transbronchial needle aspiration to further increase diagnostic yield and minimize processing complexity remains controversial. This study aims to compare aspiration biopsy (Endobronchial ultrasound-guided transbronchial needle aspiration) and non-aspiration biopsy (Endobronchial ultrasound-guided transbronchial needle capillary sampling) in terms of sample adequacy, diagnosis, and quality in malignant cases.

Background And Aim: Ultrasound-guided fine-needle sample collection for cytology with manual restraint is frequently used for the primary assessment of diffuse liver disease in veterinary patients in Thailand. For better diagnosis, repeated collection of samples ensures the collection of adequate, representative samples, which increase diagnostic accuracy. However, in those that are unable to receive general anesthesia, it is difficult to collect the samples from several liver locations in manually restrained dogs and cats.
