Summary of article contents:
Introduction
This study investigates the efficacy of intra-operative ultrasound (IOUS) compared to post-operative magnetic resonance imaging (MRI) for tumor resection in patients with intra-axial tumors located in the supratentorial region. Conducted between January 2016 and January 2017, the study selected a total of 20 adult patients who were informed about the procedure and provided consent. The research received approval from the Medical Research and Ethical Committee, Ministry of Health Malaysia. Each patient underwent surgery in the neurosurgery operating theatre of Kuala Lumpur Hospital, where IOUS was utilized to assist in visualizing tumor resection in real-time.
Reliability of Intra-Operative Ultrasound
One of the critical findings of the study is the high correlation between the measurements obtained from IOUS and those from MRI. Statistical analyses demonstrated that the intra-class correlation coefficient (ICC) indicates that both imaging techniques are highly reliable tools for evaluating tumor size. Regression model analysis revealed a significant correlation between IOUS and MRI, with a p-value of less than 0.05. The analysis further established that IOUS measurements were statistically equivalent to MRI, suggesting that ultrasound is capable of detecting residual tumors post-operatively with great reliability. This highlights the potential for IOUS to serve not only as an adjunct to surgery but also as a practical and effective imaging modality during operations.
Conclusion
The study concludes that IOUS is a reliable tool for aiding tumor resection during neurosurgical procedures. With its ease of availability, quicker performance, and cost-effectiveness compared to MRI, the implementation of IOUS in clinical practice for intra-operative imaging is strongly supported. The analysis indicates that ultrasound can effectively compete with MRI in the detection of residual tumors, which may enhance surgical outcomes and improve patient safety. Therefore, it is recommended that the use of IOUS becomes standard practice in surgical settings where brain tumor resection is performed.
FAQ section (important questions/answers):
What is the purpose of the study involving intra-operative ultrasound?
The study aimed to evaluate the efficacy of intra-operative ultrasound (IOUS) for tumor resection compared to post-operative MRI brain imaging in selected patients from January 2016 to January 2017.
What were the inclusion criteria for patient selection?
Patients selected for the study were adults over 18 years old with intra-axial tumors located in the supratentorial region. Those with infra-tentorial lesions or in the pediatric age group were excluded.
How was the data collected and analyzed in the study?
Data was collected through measurements using both IOUS and MRI. Statistical analyses, including the paired t-test and regression model, were performed using JMP 11 software to compare correlation and reliability between the two imaging methods.
What were the key findings regarding IOUS and MRI correlation?
The study found a significant correlation between IOUS and MRI results, indicating that IOUS is a reliable tool for detecting residual tumors post-operatively. Statistical analysis showed high correlation coefficients, supporting the equivalency of both imaging methods.

In the context of the study, tables display critical information regarding patient demographics, tumor sizes, and statistical results. Tables enhance the clarity of the research findings and enable readers to understand complex data easily.
2) Post:
Post indicates a time reference after an event or process has occurred. In this study, 'post' is used primarily in relation to postoperative evaluations, such as MRI scans conducted within 24 to 48 hours after surgery, which provide essential data for comparing the effectiveness of intra-operative ultrasound versus traditional imaging methods.
3) Study (Studying):
Study refers to a systematic investigation aimed at discovering or interpreting facts, theories, or principles. This particular study examines the efficacy of intra-operative ultrasound (IOUS) in tumor resection compared to MRIs. The study's design, implementation, and analysis are crucial for establishing new medical practices based on scientific evidence.
4) Measurement:
Measurement signifies the process of obtaining the magnitude of a quantity through standardized methods. In this research, measurements are taken to assess tumor sizes using both IOUS and MRI, allowing for objective comparisons. Accurate measurements are vital for determining the effectiveness of surgical interventions and postoperative care.
5) Reliability:
Reliability denotes the consistency of a measure or instrument over time and across different conditions. In the study, reliability is assessed through statistical analyses, such as intraclass correlation coefficients, which provide insight into the trustworthiness of the ultrasound measurements in comparison to MRI results, ensuring confidence in the study's conclusions.
6) Indian:
Indian is a term used to describe individuals or cultural elements associated with India. In the context of the study, it refers to the demographic background of some patients enrolled in the research. Recognizing the ethnicity or nationality helps in understanding the population's characteristics and potential variations in healthcare delivery outcomes.
7) Rules:
Rules refer to explicit or understood regulations guiding actions or procedures. In research, rules about inclusion and exclusion criteria for participants ensure that the study population is appropriate for answering the research question. Adhering to these rules is critical for validity and generalizability of the findings.
