AI Article Synopsis
- Thyroid nodules are common issues, and fine-needle biopsy (FNB) is the usual method for assessing them; this study compares aspiration versus nonaspiration techniques.
- A study involving 309 patients analyzed the quality of tissue samples from both biopsy methods, with smears evaluated by a pathologist using a specific scoring system.
- The findings revealed no significant difference in the quality of samples from either technique, suggesting both are valid screening methods for checking thyroid nodules.
Article Abstract
Unlabelled: Thyroid nodules are a common pathology of the thyroid gland. Thyroid fine-needle biopsy (FNB) is a technique used as the first step in the assessment of thyroid nodules. Some au- thors have demonstrated the superiority of nonaspiration compared with aspiration biopsy.
Aim: The objective was to assess whether there are significant differences between the two thyroid biopsy techniques.
Material And Methods: The study group comprised 309 patients with thyroid nodules admitted to the Endocrinology Clinic of the Iasi "St. Spiridon "Hospital between 2005 and 2008 in which fine-needle nonaspiration or aspiration biopsy was performed. The slides were read by one pathologist. The smears were stained using the May-Grunwald-Giemsa method (MGG). The quality of smears obtained by the two sampling techniques was evaluated by using the scoring system developed by Mair.
Results And Discussion: No differences in smear quality between the two sampling techniques in terms of blood contamination, amount of cellular material, degree of cellular degeneration, degree of cellular trauma, and preservation of appropriate architecture were found.
Conclusion: The results of this study show that the sensitivity and specificity of both techniques allow their use as standard screening methods for thyroid nodular lesions.

A radiopathomics model for predicting large-number cervical lymph node metastasis in clinical N0 papillary thyroid carcinoma.
Eur Radiol
January 2025
Department of Ultrasound, Chengdu Second People's Hospital, Chengdu, China.
Objectives: This study aimed to develop a multimodal radiopathomics model utilising preoperative ultrasound (US) and fine-needle aspiration cytology (FNAC) to predict large-number cervical lymph node metastasis (CLNM) in patients with clinically lymph node-negative (cN0) papillary thyroid carcinoma (PTC).
Materials And Methods: This multicentre retrospective study included patients with PTC between October 2017 and June 2024 across seven institutions. Patients were categorised based on the presence or absence of large-number CLNM in training, validation, and external testing cohorts.

Rijnstate, Dept. of Radiology and Nuclear Medicine, Arnhem, The Netherlands.
Context: Radiofrequency ablation (RFA) is used as treatment for symptomatic thyroid nodules. Factors influencing the volume reduction ratio (VRR) at 12 months are not yet fully understood.
Objective: The primary objective was evaluating the VRR at 12 months after RFA.
The natural history of cytologically low-risk indeterminate thyroid nodules.
J Clin Endocrinol Metab
January 2025
Department of Internal Medicine and Therapeutics, University of Pavia, 27100 Pavia, Italy.
Background: Thyroid nodules classified cytologically as low-risk indeterminate lesions (TIR3A) on fine-needle aspiration biopsy (FNAB) present a clinical challenge due to their uncertain malignancy risk. This single-center study aimed to evaluate the natural history of TIR3A nodules.
Materials And Methods: FNABs performed between July 2017 and December 2019 were retrospectively retrieved and patients with TIR3A nodules were evaluated at baseline and throughout a follow-up based on ultrasound (US) parameters and clinical data.
Parathyroid Adenoma at the Parapharyngeal Space Detected on 99mTc-Sestamibi SPECT/CT.
Clin Nucl Med
January 2025
From the Nuclear Medicine Unit, Department of Diagnostic and Interventional Radiology, Queen Elizabeth Hospital, Hong Kong.
A 77-year-old woman was diagnosed with primary hyperparathyroidism, and initial cervical ultrasonography found no parathyroid lesion, and she was referred to the nuclear medicine unit for dual-phase 99mTc-sestamibi (MIBI) scan. The scintigraphy unveiled heterogeneous uptake patterns across bilateral thyroid lobes, corresponding to the thyroid nodules, alongside a marked focal uptake with delayed tracer washout in the right oral region. The SPECT/CT pinpointed a MIBI-avid nodule within the right parapharyngeal space, indicative of parathyroid ectopia.
