Summary
Cryoablation is a safe and feasible treatment for lung ground-glass opacities (GGO). This minimally invasive procedure showed no serious complications and effectively ablated GGO in all patients within 24 months.
Area of Science:
- Pulmonology
- Oncology
- Interventional Radiology
Background:
- Ground-glass opacity (GGO) is a non-specific indicator of early-stage lung cancer.
- Early diagnosis and prompt surgical intervention are crucial for favorable outcomes in GGO cases.
Purpose of the Study:
- To evaluate the safety and feasibility of cryoablation for treating lung GGO.
- To assess the efficacy of cryoablation in GGO treatment.
Main Methods:
- Retrospective review of clinical data from 14 patients with 19 lung GGO lesions.
- Evaluation of adverse events, pulmonary function, and treatment outcomes post-cryoablation.
- Statistical analysis using SPSS software (version 13.0).
Main Results:
- No serious complications were reported in any patients undergoing cryoablation.
- Pulmonary function returned to over 95% of baseline within one month post-treatment.
- Computed tomography scans at 24-month follow-up confirmed successful ablation of all GGO lesions.
Conclusions:
- Cryoablation presents a safe and viable therapeutic option for lung GGO.
- The procedure demonstrates high efficacy and good tolerability in patients with GGO.

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

01:28The Looking Glass Self
326
The concept of the looking-glass self describes how an individual's self-concept is shaped by their perception of how others see them. This psychological theory, first introduced by sociologist Charles Horton Cooley in 1902, posits that self-identity emerges in a social context and is influenced by the judgments—real or imagined—of others.Research suggests that individuals frequently overestimate how positively others perceive them. This is particularly evident in physical...

01:21Pilot and Numeric Relaying
487
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

01:12Taping Over Different Ground Profiles
358
Taping over varying ground profiles requires careful adaptation to achieve accurate measurements. On smooth, level ground with minimal vegetation, the tape can rest directly on the ground. Here, the taping team, typically consisting of a head and a rear tapeman, coordinates their positions with clear communication. The rear tapeman holds the tape at the starting point and guides the head tapeman toward a range pole placed beyond the endpoint, using hand or voice signals to ensure alignment.On...

The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.
