What does KATHRYN FOWLER research?

Dr. Fowler's research primarily involves studying how imaging technologies can be utilized to better identify and manage cancers, especially liver cancer, colorectal cancer, and conditions related to liver health such as steatotic liver disease. She looks at sophisticated imaging techniques like CT scans, MRIs, and ultrasound to detect cancer, monitor its progression, and inform treatment decisions. Her work is crucial not only for cancer patients but also for those undergoing transplants and weight-loss surgeries, ensuring that healthcare providers have the best information to guide their care. Additionally, Dr. Fowler is involved in evaluating how patients’ experiences and recovery progress after major surgeries, such as kidney transplants and bariatric procedures, can be better understood and enhanced through appropriate medical imaging. By making sense of the data collected through imaging, she aims to elevate the standard of care received by patients in these critical areas.

Key findings

  • In her study on Yttrium-90 radioembolization for liver cancer, 29 out of 43 patients (67%) achieved a complete cancer response, with a specific radiation dose level predicting 88% success.
  • Research on imaging for hepatocellular carcinoma showed the ability to predict tumor types and patient responses, significantly impacting treatment decisions.
  • The ACR guidelines she contributed to indicated that using a coordinated approach among specialists improved patient survival rates in liver cancer cases.

This study looked at how well multiple healthcare professionals agreed on liver imaging assessments using the LI-RADS system, which categorizes liver lesions based on their likelihood of being cancerous. Researchers analyzed data from 484 patients, finding moderate agreement on the LI-RADS categories, with scores indicating reader agreement ranging from 0.46 to 0.68 on a scale where 1 represents perfect agreement. This matters because consistent evaluation is crucial for accurate diagnosis and treatment planning for patients with liver conditions. Who this helps: This helps doctors and radiologists involved in diagnosing liver diseases.
