Article Abstract
Background/aim: Cervical selective nerve root block (CSNRB) is a widely used percutaneous procedure to diagnose and treat cervical radicular pain. The feasibility of a three-dimensional puncture planning and two-dimensional laser-guidance system has previously been shown in an model. The purpose of this study was to further compare this technique to the conventional computed tomography (CT-)-guided approach.
Materials And Methods: Thirty CSNRBs were performed, each with Dyna-CT and the Syngo iGuide laser-guidance system (Artis Zee Ceiling, Siemens Medical Solutions, Erlangen, Germany), and with conventional CT-guidance (Somatom Volume Zoom, Siemens Healthcare, Erlangen, Germany) in an lamb model. The number of puncture attempts, procedural planning time, puncture time, and trajectory length were evaluated and compared.
Results: All 60 punctures were rated as successful. Significantly less puncture attempts were needed with Dyna-CT compared to conventional CT-guidance (<0.0001). Procedural planning time and puncture time were significantly shorter with Dyna-CT ( <0.0001 and =0.0004) (median 77 s and 56 s, respectively) than with conventional CT-guidance (median 109 s and 159.5 s, respectively), There were no significant differences in trajectory length (Dyna-CT median 3.18 cm; conventional CT median 3.33 cm, =0.651).
Conclusion: Dyna-CT with Syngo iGuide laser-guidance is superior to conventional CT-guidance for CSNRB in an model. It significantly shortens the overall procedure time by reducing planning time, puncture time, and puncture attempts.

Three-dimensionally printed navigational template technology for lung biopsy: a non-inferiority, randomised trial.

Department of Thoracic Surgery, Shanghai Pulmonary Hospital, Tongji University School of Medicine, Shanghai, China.
Background: Percutaneous transthoracic lung biopsy (PTNB) guided by Computed Tomography (CT) greatly depends on the operators' skill for accuracy. This study aimed to evaluate whether three-dimensionally(3D) printed navigational templates for percutaneous transthoracic lung biopsy achieve diagnostic yield comparable to conventional computed tomography guidance.
Materials And Methods: Conducted from 1 November 2020, to 27 July 2023, this noninferiority randomized clinical trial included 159 patients with peripheral lung masses (≥30 mm).
Rare Case Report of Pulmonary Mucosa-Associated Lymphoid Tissue Lymphoma.
Respirol Case Rep
August 2025
Bronchial mucosa-associated lymphoid tissue is the site of the uncommon malignancy known as mucosa-associated lymphoid tissue (MALT) lymphoma. Due to its lack of distinct clinical signs and imaging characteristics, it is frequently misdiagnosed and underdiagnosed. After receiving unsuccessful treatment for a lung infection or tuberculosis in multiple tertiary care hospitals, we report a male patient who had a solid lesion in his left upper lung for 18 years.

Introduction: Head and neck cancer (HNC) treatment on the Unity MR-Linac (MRL) (Elekta AB, Stockholm, Sweden) has been developed using the novel adapt-to-shape Lite (ATS-lite) method to create clinically acceptable adaptive treatments clinician-free. Here we investigate patient experience and acceptability of this technique.
Methods: Ten HNC patients treated to 65 Gy in 30 fractions with MRI-guided adaptive radiotherapy (MRIgART) within the PERMIT trial (NCT03727698), were included.
The Added Benefits of Performing Liver Tumor Ablation in the Angiography Suite: A Pictorial Essay of Combining C-Arm CT Guidance with Hepatic Arteriography for Liver Tumor Ablation.

The HepACAGA (Hepatic Arteriography and C-arm CT-Guided Ablation) technique, which integrates C-arm CT guidance with transcatheter C-arm CT hepatic arteriography (C-arm CTHA), significantly improves liver tumor ablation outcomes by enhancing tumor visualization, navigation, and the intraprocedural assessment of ablation margins. The two key advantages of using C-arm CT over conventional CT for image guidance are firstly that the entire procedure can be performed in the angiography suite, eliminating the need for patient transfer between the angiography suite (catheterization) and CT-room (ablation), and secondly, that integrated C-arm needle guidance software can greatly reduce the difficulty of needle placement. Beyond these advantages, the HepACAGA technique offers additional benefits across four domains: (1) the direct conversion of ablation to intra-arterial liver-directed therapies (e.

Objectives: Conventional bladder tumor diagnosis consists of transurethral resections, which are not always feasible and can entail significant morbidity for vulnerable patients. This study was conducted to evaluate the safety and diagnostic yield percutaneous urinary bladder tumor biopsy as an alternative for such cases.
Methods: Retrospective review of an institutional database identified 58 patients who underwent 59 bladder tumor biopsies between February 1, 2009 and February 1, 2025.
