Patient Advocacy Advisory Board

One of SNMMI’s goals is to engage the patient community and provide information about the uses of molecular imaging for improved diagnosis and treatment. The Society is committed to supporting patients, collaborating with patient advocacy organizations on issues of mutual interest, and providing educational programs to help patients understand molecular imaging and the role it can play in both diagnostic and therapeutic settings. To accomplish this, we have convened a Patient Advocacy Advisory Board to provide SNMMI staff, volunteer leaders, and members with the patient perspective. One of the board's first initiatives was to develop this website — a user-friendly resource about molecular imaging and therapy and those disease areas that are using molecular imaging. The content of this website has been reviewed, and will continue to be updated, by experts in the fields of nuclear medicine, cardiology, neurology, and oncology.

Vice Chair
Colon Cancer Alliance
Dorothy McGrath is a Stage IV colon cancer survivor.  When she was initially diagnosed in 2004, on her birthday, she wasn’t offered much hope for survival.  Being a researcher at heart, having worked at PBS affiliates for over 26 years, she educated herself on the disease and signed up for a Stage II clinical trial.  While researching her disease she joined the Colon Cancer Alliance and has been a mentor, advocate and speaker about this disease in order to raise awareness.  Her passion for producing health related programs for her local PBS station escalated.  Now that she is an insider on the disease, she has a true understanding of the challenges that patients face.  She hopes that her productions are more informative to meet the patients, and their caregiver’s needs.

Theresa Wickerham Theresa Wickerham
ThyCa: Thyroid Cancer Survivors' Association
Theresa Wickerham began volunteering for ThyCa: Thyroid Cancer Survivors’ Association in 2000. Following her original thyroid cancer diagnosis in 1975 she went 25 years without meeting anyone with thyroid cancer. She had a recurrence in 1998. During this more recent treatment experience she found some information about thyroid cancer on the Internet and also virtually met thyroid cancer survivors. This empowerment helped her realize that no one should go through a thyroid cancer diagnosis and journey alone and without the knowledge necessary to make good choices. She decided to get involved and make a difference. She founded the St. Louis Thyroid Cancer Survivors’ Support Group, organized several one-day regional workshops throughout the Midwest, and has taken on more and more involved planning and coordination roles in ThyCa’s International Thyroid Cancer Survivors’ Conferences including hosting the meeting in St. Louis, Missouri, in 2008 and 2015. In 2012 Theresa took the position of Program Coordinator for ThyCa. In this role she furthers education and support programs for all people dealing with a thyroid cancer diagnosis. She lives outside of St. Louis, Missouri, with her husband and enjoys spending time with their children and grandchildren.
