During the last 30 years, the techniques of percutaneous biopsy have evolved dramatically and its indications have expanded accordingly. Additionally, recent treatments in oncology have made it necessary to use larger cutting needles in biopsies for tissue analysis. These developments force radiologists to perform biopsies in areas they are not very familiar with. However, lesions in such organs and regions are traditionally considered to be dangerous because of the risk of bleeding and trauma to the critical structures along the needle tract. As a result, radiologists are generally reluctant to perform image-guided biopsies in such locations particularly using cutting needles. We present the images of nine cases from our archive, in whom we performed image-guided percutaneous cutting needle biopsy (PCNB) for lesions located in larynx, tongue, intestines, stomach, deep pelvis, uterus, pancreas, penis and spleen. For each specific location, we also mention alternative biopsy methods, the indications of PCNB, its potential risks and special techniques to avoid complications.

Aims: Brachytherapy is advantageous for localised rhabdomyosarcomas in children compared with external beam radiotherapy, sparing close organs at risk with highly conformal dosimetry. A methodology for planning and delivering fractionated high-dose-rate paediatric pelvic brachytherapy is detailed, and the dosimetric parameters are presented. This provides a practical template for radiotherapy departments with a similar patient cohort to implement this treatment technique.

Objective: To maximize local tumor control, stabilize affected bones, and preserve or replace joints with minimal interventional burden, thereby enhancing quality of life for empowered living.
Indications: Suitable for patients with bone metastases, particularly those with severe pain and/or fractures and appropriate life expectancy.
Contraindications: In primary bone tumors, refer to the sarcoma surgery team for evaluation of wide resection.
Purpose: To evaluate the diagnostic yield and safety profile of percutaneous image-guided biopsy of mesenteric lesions.
Materials, Methods, And Procedures: Image-guided percutaneous biopsies of the mesentery at a single institution from 2000 to 2022 were identified and reviewed. Relevant demographic and procedural data were abstracted from the medical record.
Safety and Efficacy of Percutaneous Drain Placement for Postsurgical Breast Region Fluid Collections.

Department of Radiology, Stanford Medicine, Stanford, CA, USA.
Objective: The purpose of this study was to describe the safety and efficacy of percutaneous drain placement for postoperative fluid collections in the breast.
Methods: A retrospective review was conducted of the patient characteristics, intervention data, and clinical outcomes of the 43 adult patients who underwent percutaneous drain placement for fluid collections at a tertiary care hospital over a 13-year period ending February 28, 2023.
Results: Most fluid collections treated with percutaneous drain placement were secondary to ipsilateral breast surgery (92%, 44/48), most commonly breast reduction (23%, 10/44) and mastectomy with immediate tissue expander reconstruction (16%, 7/44).
A Respiratory Signal Monitoring Method Based on Dual-Pathway Deep Learning Networks in Image-Guided Robotic-Assisted Intervention System.
Int J Med Robot
December 2024
School of Automation, Nanjing University of Information Science and Technology, Nanjing, China.
Background: Percutaneous puncture procedures, guided by image-guided robotic-assisted intervention (IGRI) systems, are susceptible to disruptions in patients' respiratory rhythm due to factors such as pain and psychological distress.
Methods: We developed an IGRI system with a coded structured light camera and a binocular camera. Our system incorporates dual-pathway deep learning networks, combining convolutional long short-term memory (ConvLSTM) and point long short-term memory (PointLSTM) modules for real-time respiratory signal monitoring.
