The fine needle biopsy is an important minimally invasive procedure for providing accurate diagnosis in cases of thyroid gland nodules. This paper presents the research, development and evaluation of a virtual reality simulator for the training of ultrasound guided needle biopsy of thyroid gland nodules, using 3D models and haptic devices. The system is also an educative tool, where the user can interact with a thyroid 3D model to feel its texture, as well as rotate a complete model of the neck with transparency in order to study all its internal organs.

Validation of Risk Prediction Models for Pneumothorax and Intercostal Catheter Insertion Following CT-Guided Lung Biopsy.
J Med Imaging Radiat Oncol

Department of Radiology, Grampians Health, Ballarat Central, Victoria, Australia.
Background: CT-guided percutaneous transthoracic needle biopsy is the primary method for diagnosing lung lesions. Widely accepted validated risk prediction models are yet to be developed. A recently published study conducted at Grampians Health Services (GHS) developed two risk prediction models for predicting pneumothorax and intercostal catheter (ICC) insertion.

Hibernomas are rare, benign neoplasms characterized by the presence of brown adipose tissue. Although these tumors may arise in any region of brown fat, they predominantly occur in the thigh, shoulder, back, and neck. Hibernomas are rarely found in mammary tissue, with a higher prevalence in females than males.

Department of Radiology, Karolinska University Hospital, Stockholm, Sweden; Department of Oncology and Pathology, Karolinska Institutet, Stockholm, Sweden.
Background: Utilizing a larger needle-size instead of a smaller one in vacuum-assisted excision of breast lesions might enhance the effectiveness of the method. We conducted a clinical trial to investigate the effects of needle size 7G compared to 10G regarding excision completeness and procedural efficiency.
Materials And Methods: In this prospective, single-blinded, randomized clinical trial, the patients were enrolled between November 2019 and August 2022.
K-Wire-Assisted Intra-axial Intradural Approach for Cavernous Sinus Biopsy: A Case Report.

Neurosurgery, University of Illinois College of Medicine Peoria, Peoria, USA.
Petroclival approaches remain challenging given abundant cranial nerves and vessels. Common trajectories include transsphenoidal, transoral, middle fossa-extradural, and posterior through the cerebellar peduncle. We report a unique intra-axial, intradural approach to the petroclival and cavernous sinus.
