Intraoperative MRI (iMRI) has emerged as a groundbreaking technology in the field of neurosurgery, allowing for real-time imaging that significantly enhances surgical accuracy and patient safety. At the Atlas Institute of Brain and Spine in Los Angeles, we harness the power of advanced imaging techniques to assist in even the most complex brain surgeries. Under the leadership of Dr. Aaron Cohen-Gadol, founder and president of the Atlas Institute and an internationally recognized leader in complex brain surgery, our practice is at the forefront of this innovative technology, providing unparalleled care to patients facing significant challenges.
Dr. Cohen is the best of the best of the best. I had a large tumor (42.85mm x 37.79mm) pressing against my brain. I was referred to Dr. Cohen, who reviewed my scans and gave me the peace of mind that he could remove the tumor. Dr. Cohen was very kind and patient with me and even took the time to have a virtual appointment with my wife and I to answer several questions and concerns we had.
There are many attributes that describe Dr. Cohen: he is incredibly skillful, he has a tremendous bedside manner, he is kind and wants what is best for his patients.
What is Intraoperative MRI and How Does it Work
Intraoperative MRI is an advanced imaging technique that allows neurosurgeons to obtain detailed images of the brain during surgery. This technology enables real-time visualization without the need to awaken the patient, facilitating precise targeting of lesions. By integrating iMRI into surgical procedures, our team can make informed decisions based on the most current data, minimizing the risks associated with complex surgeries such as tumor removals. The combination of iMRI and Dr. Cohen-Gadol’s extensive experience in performing over 7,500 complex brain surgeries enhances the precision and safety of each procedure.
Benefits of Real-Time Imaging in Neurosurgery
The use of intraoperative MRI offers numerous advantages in neurosurgery, including:
- Enhanced surgical accuracy through real-time imaging.
- Reduced need for additional anesthetic sessions.
- Lower risk of complications during and after surgery.
- Improved patient outcomes through precise lesion targeting.
- Increased rates of gross total resection, providing potential survival benefits for patients undergoing glioma surgery.
These benefits make iMRI a vital tool for neurosurgeons dedicated to achieving the highest standards of patient care in Los Angeles.


Enhancing Surgical Accuracy with Advanced Imaging
Advanced imaging technologies such as iMRI revolutionize surgical planning and execution. With high-resolution imaging capabilities, this technique provides a clear view of the surgical field, allowing for better identification of tumors and critical neural structures. iMRI facilitates the detection of brain shift during surgery, enabling our neurosurgeons to adjust their approach and improve tumor resection outcomes dynamically. At the Atlas Institute, incorporating iMRI enables our surgeons to adapt their strategies during procedures, thereby enhancing overall surgical outcomes.
How iMRI Supports Tumor Removal Procedures
During tumor removal surgeries, intraoperative MRI is integral in ensuring maximal safe resection while preserving neurologic function. By providing immediate feedback on surgical progress, iMRI can help our neurosurgeons identify and remove all tumor tissue effectively while minimizing damage to surrounding healthy brain matter. This approach is particularly beneficial for complex cases and recurrent tumors often deemed inoperable.
Importance of Surgical Planning in Brain Surgery
Effective surgical planning is crucial for successful outcomes in brain surgery. The incorporation of iMRI into our surgical framework allows us to visualize the brain pre-operatively and adapt our plans in real-time during surgery. This facilitates more precise interventions, reduces the likelihood of complications, and assures patients that their individual needs are being prioritized. By combining meticulous planning with advanced imaging, we can achieve optimal results for residents throughout Los Angeles and beyond.
How Advanced Imaging Improves Patient Care
At the Atlas Institute of Brain and Spine, we believe that advanced imaging technologies directly enhance patient care. Our approach marries cutting-edge technology with compassionate attention, ensuring that every patient receives personalized treatment tailored to their unique circumstances. Advanced imaging helps mitigate risks, streamline surgical processes, and improve overall patient satisfaction. The incorporation of such technology is a reflection of our commitment to advancing neurosurgical practices that prioritize patient safety.
