Objective: The study aims to evaluate the clinical efficacy of CT-guided radiofrequency ablation in conjunction with targeted therapy in lung cancer patients.
Method: We retrospectively analyzed 80 lung cancer patients. They were stratified into the Observation Group (OG, n=40, treated with CT-guided radiofrequency ablation in conjunction with targeted therapy) and the Control Group (CG, n=40, treated solely with targeted therapy).
Results: The OG group reported 4 cases of Complete Response (CR), 24 cases of Partial Response (PR), 10 cases of Stable Disease (SD), and 2 cases of Progressive Disease (PD). The Overall Response Rate (ORR) was 70.00% (28/40), and the Disease Control Rate (DCR) was 95.00% (38/40). In contrast, the CG group exhibited 3 cases of CR, 20 cases of PR, 12 cases of SD, and 5 cases of PD. The ORR was 57.50% (23/40), and the DCR was 87.50% (35/40). The ORR and DCR in the OG group were significantly higher than those in the CG group. After 6 weeks of treatment, the levels of SCC, CEA, and CA125 in the OG group were significantly lower than those in the CG group; The CD4+ levels in the OG group were significantly higher and the CD8+ levels significantly lower than those in the CG group. A 24-month follow-up showed that the survival rate of the OG group was 47.50% (19/40), which was significantly higher than that of the CG group at 27.50% (11/40).
Conclusion: CT-guided radiofrequency ablation and targeted therapy have been proven effective in treating lung cancer.

Palmoplantar hyperhidrosis is a functional disease with an unknown pathogenesis, making it challenging to find a lasting and effective treatment. This article reports a case of a 43-year-old patient with palmoplantar hyperhidrosis treated with computed tomography (CT)-guided radiofrequency neurotomy (RFN) of bilateral T3-4 sympathetic chain combined with bilateral L3 sympathetic ganglion. The optimal puncture level and skin entry point were selected, and measurements were taken using a CT tool to determine needle depth, angle, and distance from the midline.

Introduction: Osteoid osteoma (OO) is a benign intra-osseous lesion. The lesion is painful and usually diagnosed by x-ray, computed tomography (CT) or magnetic resonance imaging (MRI). When the lesion is juxta-articular or intra-capsular, the symptoms may present differently than the typical OO lesion and make diagnosis more challenging.

Background/objectives: Spinal metastases are a frequent and serious complication in cancer patients, often causing severe pain, instability, and neurological deficits. Thermal ablation techniques such as radiofrequency ablation (RFA), microwave ablation (MWA), and cryoablation (CA) have emerged as minimally invasive treatments. These techniques rely on precise imaging guidance to effectively target lesions while minimizing complications.

Osteoid Osteoma (OO) is a common primary bone tumor that often presents with night pain in younger orthopedic patients. Although typically extra-articular, intra-articular presentations may be difficult to diagnose. While magnetic resonance imaging (MRI) provides excellent detailed imaging of the articular surface, it has been reported to lead to occasional misdiagnosis given limitations in spatial resolution, particularly for smaller lesions.
