    Assessment of multifocality and axillary nodal involvement in early-stage breast cancer patients using 18F-FDG PET/CT compared to contrast-enhanced and diffusion-weighted magnetic resonance imaging and sentinel node biopsy

    Background: Non-invasive evaluation of the extent of axillary nodal involvement in early-stage breast cancer (ESBC) patients and accurate assessment of multifocality are both challenging. Few reports have explored whether 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) might be more useful than other diagnostic methods in these contexts.

    Incidental detection of prostate-specific antigen-negative metastatic prostate cancer initially presented with solitary pulmonary nodule on fluorodeoxyglucose positron emission tomography/computed tomography
    (2015-01-01) ERDOĞAN, EZGİ BAŞAK; Buyukpinarbasili, NUR; ZİYADE, SEDAT; AKMAN, Tolga; TÜRK, HACI MEHMET; AYDIN, MEHMET; ERDOĞAN, EZGİ BAŞAK; BÜYÜKPINARBAŞILI, NUR; ZİYADE, SEDAT; TÜRK, HACI MEHMET; AYDIN, MEHMET
    A 71-year-old male patient with solitary pulmonary nodule underwent fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) showing slightly increased FDG uptake in this nodule. In addition, PET/CT detected hypermetabolic sclerotic bone lesions in the right second rib and 7(th) thoracic vertebrae, which were interpreted as possible metastases, and mildly increased FDG uptake in the prostate gland highly suspicious of malignancy. The patient's prostate-specific antigen (PSA) level was within normal range (3.8 ng/dL). The histopathological examination of the lung nodule and right second rib lesion proved metastases from prostate cancer, then the prostate biopsy-confirmed prostate adenocarcinoma. The unique feature of this case is to emphasize the importance of performing PET/CT for solitary pulmonary nodule in detecting PSA-negative metastatic prostate cancer. This case indicated that it should be kept in mind that, even if the PSA is negative, a lung metastasis of prostate cancer may be an underlying cause in patients evaluated for solitary pulmonary nodule by FDG PET/CT.

    Investigation of Added Value of Imaging Performed in a Prone Position to Standard 18 F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography Imaging for Staging in Patients with Breast Cancer
    (2022-02-02T00:00:00Z) Erdoğan, Ezgi Başak; Aydın, MEHMET; ERDOĞAN, EZGİ BAŞAK; AYDIN, MEHMET
    Objectives: To investigate whether additional imaging in a prone position has any value to the supine whole-body 18fluorine-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) images by comparing the visual and quantitative data about a local disease in the breast and axilla for the initial staging of breast cancer (BC). Methods: In this study, a total of 91 female patients with the BC were studied. Both the supine and prone images were examined based on the axial diameter, number and location of the primary tumor, local invasion signs of the tumor, the number of axillary lymph nodes with a suspected metastasis, metabolic parameters of the primary tumor and axillary lymph nodes, and registration artifacts of the PET and CT images were evaluated individually. These findings were compared with the histopathological data obtained after a surgery. Results: In the evaluation of a supine and prone imaging, tumor diameter and metabolic tumor volume (MTV) values of the breast lesions were greater in the supine position than in the prone position. However, there was no significant difference found between the other metabolic parameters of a primary tumor and axilla in both positions. In the supine and prone images, accuracy for skin involvement was 84% and 91.3%, respectively. Conclusion: In our study, we observed that, obtaining additional images in the prone position does not significantly benefit the evaluation of a local disease. The average values of the primary tumor diameter and MTV in the prone position appear to be smaller than the one in the supine position. However, the prone imaging in the patients with a newly diagnosed BC may be beneficial in selected patients and may contribute to preventing the false-positive results especially in patients with a suspected skin involvement. Keywords: 18F-fluorodeoxyglucose (18F-FDG); Breast cancer; positron emission tomography/computed tomography (PET/CT); prone position.

    Synchronous Hepatocellular Carcinoma and Cholangiocellular Carcinoma on F-18-FDG PET/CT
    (2018-10-01) Erdogan, EZGİ BAŞAK; Turk, HACI MEHMET; Tekce, ERTUĞRUL; Aydin, MEHMET; ERDOĞAN, EZGİ BAŞAK; TÜRK, HACI MEHMET; AYDIN, MEHMET
    A 43-year-old male patient presented with a mass lesion on the right liver lobe, segment 5, in radiological imaging and elevated alpha-fetoprotein levels (323 ng/mL) compatible with hepatocellular carcinoma (HCC). Positron emission tomography/computed tomography (PET/CT) images showed background level 18F-FDG uptake in the mass lesion. In addition, a secondary focus of increased 18F-FDG uptake was detected on the left liver lobe, segment 2, approximately 1,5 cm in diameter. Histopathological examination revealed HCC in the larger mass lesion with a lower 18F-FDG uptake, and cholangiocellular carcinoma in the smaller mass lesion with a higher 18F-FDG uptake. To our knowledge, this is the first case report of two histopathologically different primary malignant liver tumors in two distinct segments of the liver detected by PET/CT.

    Radyofarmasötiklerin Üretiminde ve Klinik Kullanımında Radyasyon Korunması
    (2019-12-01) Erdoğan, Ezgi Başak; Aydın, Mehmet; ERDOĞAN, EZGİ BAŞAK; AYDIN, MEHMET
    Radyonüklid moleküler görüntüleme, biyolojik süreçlerin görüntülenmesi, karakterizasyonu ve ölçümünü sağlamakta olup, bu alan ilerlemeye ve gelişmeye devam etmektedir. Son zamanlarda geliştirilen hibrit görüntüleme sistemleri sayesinde, hem fonksiyonel hem de morfolojik bilgilerin aynı anda elde edilmesi tanısal yaklaşıma çok önemli katkı sağlamıştır. Bu sistemlerde, halen en yaygın olarak kullanılan radyofarmasötik F-18 ile işaretli glukoz analoğu olan F-18 florodeoksiglukozdur (FDG). Bu yazıda, pozitron emisyon tomografi (PET) görüntülemede kullanılan başlıca radyofarmasötiklerin görüntüleme mekanizmaları ve klinik uygulama alanları kısaca özetlenmeye çalışıldı.
