A Guide to Writing Academic Portfolios for Radiologists.

The academic educator's portfolio is a collection of materials that document academic performance and achievements, supplementing the curriculum vitae, in order to showcase a faculty member's most significant accomplishments. A decade ago, a survey of medical schools revealed frustration in the nonuniform methods of measuring faculty's medical education productivity. A proposed solution was the use of an academic educator's portfolio.

All You Need to Know as an Authorized User.

Objective: The purpose of this article is to review the training requirements for practicing nuclear radiology, the scope of licensing, how to start a new practice, and the key concepts an authorized user needs to know for responsible use of radiopharmaceuticals.

Conclusion: Physicians responsible for the daily operations of nuclear medicine clinics often find the regulations concerning the safe handling and administration of radiopharmaceuticals daunting. Even experienced authorized users have concerns about handling many new therapeutic agents.

Ovarian hyperstimulation and breast cancer on PET imaging with sonographic correlation.

We present interesting PET/CT and ultrasound findings in a 36-year-old lactating woman with stage T2 N0 M0 right breast cancer undergoing oocyte retrieval for fertility preservation. Her cancer treatment plan included neoadjuvant chemotherapy; therefore, the patient wanted to undergo an oocyte retrieval procedure for fertility preservation. She underwent a transvaginal ultrasound-guided oocyte retrieval procedure in the morning and a staging F-FDG PET/CT later the same day.

18F-FDG PET/CT Findings in Portal Vein Thrombosis and Liver Metastases.

(18)F-FDG PET/CT is a valuable noninvasive tool in oncologic imaging, and its application in the diagnosis of liver metastases has been very convincing. Both the sensitivity and the specificity of (18)F-FDG PET/CT are high for detecting liver metastases from various tumors including colorectal, breast, and lung. Such liver metastases are typically (18)F-FDG-avid.

¹⁸F-FDG PET and PET/CT patient preparation: a review of the literature.

For many types of cancer, (18)F-FDG PET/CT is commonly used in evaluation and management, including tumor diagnosis, staging, restaging, treatment monitoring, and radiation therapy planning. Meticulous patient preparation including restrictions of diet and activity and management of blood glucose levels in diabetic patients, as well as an awareness of the effect of medications and environmental conditions, plays an important role toward obtaining good-quality images, which are essential for accurate interpretation. Protocol guidelines for performing PET/CT have been proposed by various societies and groups, including the Society of Nuclear Medicine and Molecular Imaging, the European Association of Nuclear Medicine, the American College of Radiology, and the National Cancer Institute.

Evaluation of tumor-induced osteomalacia with 111In-pentetreotide scintigraphy.

In cases of nonhereditary osteomalacia associated with hypophosphatemia and inadequate response to vitamin D supplementation, one should consider the possibility of tumor-induced osteomalacia, a paraneoplastic syndrome caused by small mesenchymal tumors often found in obscure locations. We present a case of tumor-induced osteomalacia in which (111)In-pentetreotide scintigraphy aided in accurate localization of the culprit brachial plexus tumor and cure after resection.

Primary hyperparathyroidism-related brown tumors mimicking other giant cell-containing skeletal tumors: role of correlative imaging in diagnosis.

A patient initially suspected of having a giant cell granuloma was subsequently found-through additional imaging with (99m)Tc-sestamibi and ultrasound-to have osteolytic brown tumors caused by a parathyroid adenoma. Brown tumors that relate to primary hyperparathyroidism may mimic other skeletal tumors that contain giant cells, presenting difficulty with accurate diagnosis. Correlative imaging can have a valuable role in such cases, potentially avoiding the extensive work-up usually done for suspected bone metastases.

Radiation necrosis in the brain: imaging features and differentiation from tumor recurrence.

Radiation necrosis in the brain commonly occurs in three distinct clinical scenarios, namely, radiation therapy for head and neck malignancy or intracranial extraaxial tumor, stereotactic radiation therapy (including radiosurgery) for brain metastasis, and radiation therapy for primary brain tumors. Knowledge of the radiation treatment plan, amount of brain tissue included in the radiation port, type of radiation, location of the primary malignancy, and amount of time elapsed since radiation therapy is extremely important in determining whether the imaging abnormality represents radiation necrosis or recurrent tumor. Conventional magnetic resonance (MR) imaging findings of these two entities overlap considerably, and even at histopathologic analysis, tumor mixed with radiation necrosis is a common finding.

Pilot trial of preoperative (neoadjuvant) letrozole in combination with bevacizumab in postmenopausal women with newly diagnosed estrogen receptor- or progesterone receptor-positive breast cancer.

Introduction: Tumor content or expression of vascular endothelial growth factor (VEGF) is associated with impaired efficacy of antiestrogen adjuvant therapy. We designed a pilot study to assess the feasibility and short-term efficacy of neoadjuvant letrozole and bevacizumab (anti-VEGF) in postmenopausal women with stage II and III estrogen receptor/progesterone receptor-positive breast cancer.

Patients And Methods: Patients were treated with a neoadjuvant regimen of letrozole orally 2.
