ABSTRACT: Approximately 30% of thyroid cancer patients present with reappearing disease within 40 years of initial diagnosis. Hence, sensitive postsurgical monitoring techniques are imperative to successful long-term care. The objective of this study was to assess the added clinical utility of a combined positron emission tomography/magnetic resonance imaging (PET/MRI) of the neck in conjunction with standard imaging in the detection of recurrent thyroid carcinoma. We define standard imaging as a neck sonogram, 131I scan, computed tomography, and MRI. This study included 34 patients treated for thyroid cancer at Washington Hospital Center. All patients had previously undergone near-total or total thyroidectomy, standard follow-up imaging studies, and laboratory studies. Twenty-nine of thirty-four patients had received at least one 131I treatment prior to the study. Each patient received a PET and MRI scan, and these images were subsequently digitally fused. Individually and blinded, four endocrinologists retrospectively reviewed all information in patient charts prior to PET and PET/MRI coregistration. A clinical assessment and treatment plan were devised with these data. Following the initial assessment, the endocrinologists were provided results from the PET and PET/MRI fusion studies and asked to make a revised assessment and treatment plan. For each patient, the physicians categorized PET/MRI fusion results as providing new information that altered the initial treatment plan, providing new information that confirmed the initial treatment plan, or providing no additional information. On average, PET/MRI coregistration provided additional information that altered the treatment plan in 46% of the cases, provided additional information that confirmed the treatment plan in 36% of cases, and did not provide any additional information in 18% of cases. The combination of structural and functional data that PET/neck MRI fusion offers provided further information in an overwhelming majority of thyroid cancer patients in this study. Thus PET/MRI can be a useful tool in surgical planning, radioactive iodine therapy decisions, and determining the level of follow-up necessary for each patient.
Article: Hypothyroidism[Show abstract] [Hide abstract]
ABSTRACT: Hypothyroidism is one of the most common disorders encountered in an endocrine office practice. This article reviews the epidemiology, etiology, clinical presentation, diagnosis, and treatment of hypothyroidism. We emphasize some of the more recent issues, such as combination thyroid hormone therapy, management of hypothyroidism during pregnancy, and the management of subclinical hypothyroidism.
