1. The effect of positron emission tomography/computed tomography in axillary surgery approach after neoadjuvant treatment in breast cancer
SUMMARY OBJECTIVE: The aim of this study was to determine the role of positron emission tomography/computed tomography in the decision to perform axillary surgery by comparing positron emission tomography/computed tomography findings with pathology consistency after neoadjuvant chemotherapy. METHODS: Patients who were diagnosed for T1-4, cN1/2 breast cance

2. A novel labeling modality of intra-abdominal lesions with Magseed magnetic marker and extirpation by Sentimag probe navigation
SUMMARY OBJECTIVE: This study aimed to evaluate our experience with the use of Magseed, the magnetic metallic marker, as a localization technique followed by Sentimag probe detection in patients with solitary intra-abdominal local metastases with subsequent resection of the lesions. METHODS: Five patients underwent resection after the lesion was marked wit

3. Clinical and radiological characteristics of pulmonary actinomycosis mimicking lung malignancy
SUMMARY INTRODUCTION: Pulmonary actinomycosis, clinically and radiologically, mimics abscess, tuberculosis, and lung malignancy, resulting in misdiagnosis or delay in diagnosis. In this study, we analyzed the clinicoradiological features of pulmonary actinomycosis, the presence of any differences between clinical prediagnosis and radiological diagnosis, and

4. The impact of multimodality integrated positron emission tomography-computed tomography on improving the staging and management of head and neck malignancy: a cross- sectional study
ABSTRACT BACKGROUND: Clinical assessment of head and neck cancers is highly challenging owing to the complexity of regional anatomy and wide range of lesions. The diagnostic evaluation includes detailed physical examination, biopsy and imaging modalities for disease extent and staging. Appropriate imaging is done to enable determination of precise tumor ext

5. Extraparotid Warthin Tumors Imitating Metastasis of Oral Cancers
Abstract Introduction Extraparotid Warthin tumor (WT) is a very rare entity, especially when synchronous with oral cancer (OC). Objective The present study presents a case series of extraparotid WTs detected in the surgical specimen of patients treated for OC. Methods From 2007 to 2016, 336 patients were operated for OC in our institution. Neck dissection

6. Performance of 68Ga-labeled prostate-specific membrane antigen ligand positron emission tomography/computed tomography in the diagnosis of primary prostate cancer: a systematic review and meta-analysis
ABSTRACT Objective: To explore the feasibility of 68Ga-PSMA PET/CT in diagnosing primary prostate cancer. Materials and Methods: Embase, PubMed and Cochrane Library databases were searched for studies published before July 2020. The studies that used 68Ga-PSMA PET/CT for detecting primary prostate cancer, and pathological biopsy as the reference standard w

7. What is the effect of tumor diameter, lymph node metastases, and SUVmax value on prognosis in limited-stage small cell lung cancer?
SUMMARY OBJECTIVE: This study was designed to investigate the link between survival and prognostic factors such as tumor size, lymph node metastasis, and metabolic activity detected on positron emission tomography/computed tomography in patients with limited-stage small cell lung carcinoma. METHODS: Patients who were admitted to our hospital with pathologi

8. Correlation between PET-CT and ct in the staging after the treatment of head and neck squamous cell carcinoma
Abstract Objective: The aim of this study is to find out if a single imaging test is enough to follow-up on an oncological post-treatment patient. In such a case, we would know which was more valuable after comparing the two, by CT or PET-CT. Methods: Between January 2012 and July 2018, we collected data from all patients with previous medical history who

9. Iatrogenic Complications During the Diagnostic Work-Up of an Inflammatory Cardiomyopathy
Abstract A 72-year-old woman was admitted for acute heart failure. The echocardiography revealed moderate depression of the left ventricular ejection fraction. Coronary disease was excluded by coronarography. Cardiac magnetic resonance showed predominantly left ventricular septal hypertrophy and severe depression of the left ventricular systolic function. Th

10. Evidence and Considerations on Treatment of Small Size Merkel Cell Head and Neck Carcinoma
Abstract Introduction Merkel cell carcinoma (MCC) is a rare and aggressive neuroendocrine malignant cancer. It is an epidermal cancer common in the head and neck. Objectives Though there is limited number of cases described in the literature for the treatment difficult to obtain. Our purpose was to present the clinical course and treatment of four patients

11. Molecular Imaging in the Diagnosis of Infectious Endocarditis - the Role of PET and SPECT
Abstract 18-fluorine-fluorodeoxyglucose positron emission computed tomography (18F-FDG PET/CT) and singlephoton emission computed tomography (SPECT) using radiolabeled white blood cells (WBC) are non-invasive techniques widely used in the diagnosis of infections, like endocarditis. The aim of our paper was to provide a systematic review of the published data

12. Follicular dendritic cell sarcoma aggravated by hyaline-vascular Castleman's disease in association with paraneoplastic pemphigus: study of the tumor and successful treatment
Abstract The authors have successfully treated and monitored a case of paraneoplastic pemphigus in association with follicular dendritic cell sarcoma aggravated by hyaline-vascular Castleman's disease. The patient was a 56-year-old female who presented with recalcitrant erosive lichen planus of the oral cavity, tongue, and genital mucosa, along with polymorp
