Juvenile papillomatosis (JP) is a very rare benign proliferative breast disease, especially in young women under 30 years of age. Its etiology is not clear yet. Although some patients have breast cancer in their family history, up to 10% breast cancer can develop in the follow-up of JP patients.

Objectives: Breast cancer is a type of cancer caused by the uncontrolled growth of cells in the breast tissue. In a few cases, erroneous diagnosis of breast cancer by specialists and unnecessary biopsies can lead to various negative consequences. In some cases, radiologic examinations or clinical findings may raise the suspicion of breast cancer, but subsequent detailed evaluations may not confirm cancer.

Purpose: The clinical management of high-risk lesions using image-guided biopsy is challenging. This study aimed to evaluate the rates at which such lesions were upgraded to malignancy and identify possible predictive factors for upgrading high-risk lesions.

Methods: This retrospective multicenter analysis included 1.

Rationale And Objectives: The aim of the present study was to investigate the association between Luminal A and Luminal B molecular subtypes and radiomic features of dynamic contrast‑enhanced magnetic resonance imaging in patients with invasive breast cancer.

Materials And Methods: Seventy-three patients with histopathologically proven invasive ductal cancer (IDC) were selected. Tumors were classified into molecular subtypes: Luminal A (estrogen receptor (ER)-positive and/or progesterone receptor (PR)-positive, human epidermal growth factor receptor type 2 (HER2) -negative, proliferation marker Ki-67<20) and Luminal B (ER-positive and/or PR-positive, HER2-positive or HER2-negative with high Ki-67 ≥20).

Granulomatous lobular mastitis (GLM) is a rare and chronic benign inflammatory disease of the breast. Difficulties exist in the management of GLM for many front-line surgeons and medical specialists who care for patients with inflammatory disorders of the breast. This consensus is summarized to establish evidence-based recommendations for the management of GLM.

Background: Apelin is a peptide that has important effects on the cardiovascular system due to its anti-atherogenic properties and regulating blood pressure. There is not enough research evaluating the effects of apelin levels on the cardiovascular system in hemodialysis (HD) and peritoneal dialysis (PD) patients concurrently. The aim of this study was to determine apelin levels in dialysis, and control groups and to investigate the relationship between apelin and carotid intima media thickness (CIMT).

Objective: The objective of this study is to investigate the ability of native T1 mapping in the determination of myocardial fibrosis in patients with surgically corrected tetralogy of Fallot (TOF).

Methods: We included 35 patients with surgically corrected TOF who underwent cardiac magnetic resonance imaging in this study. Additionally, we added pre- and post-contrast T1 mapping sequences at the right ventricular outflow tract (RVOT) and short-axis planes to the routine protocol.

Objectives: To investigate the diagnostic value of a Superb Microvascular Imaging (SMI; Toshiba Medical Systems, Tokyo, Japan) Doppler examination for distinguishing intraductal papilloma (IDP) from duct ectasia with secretion in lesions smaller than 1 cm compared to color Doppler imaging (CDI) and power Doppler imaging (PDI).

Methods: Fifty-nine lesions were evaluated by grayscale ultrasound, CDI, PDI, and SMI. Biopsied tissue samples were analyzed.

Objectives: The aim of this study was to evaluate any association between histological grade, molecular subtypes of breast cancer, and strain elastography, and to investigate whether microcalcification affects the stiffness of tumor in breast cancers with the same histological grade.

Methods: Between April 2015 and March 2016, 94 lesions of 94 patients with the diagnosis of invasive ductal carcinoma were included in the study. Strain elastography was performed on all patients before biopsy.

Background: Granulomatous mastitis (GM) is a rare inflammatory breast disease that may mimic the clinical characteristics and radiologic imaging findings of breast carcinoma. Considering the importance of making a correct diagnosis, careful radiologic evaluations and recognition of imaging features are necessary.

Objectives: The aim of this study was to review the radiological findings and diagnostic value of the imaging in GM.

Objective: To evaluate variants of the popliteal artery (PA) terminal branches with 64-multidetector computed tomographic angiography (64-MD CTA).

Materials And Methods: A total of 495 extremities (251 right, 244 left) of 253 patients undergoing a 64-MD CTA examination were included in the study. Of these, 242 extremities were evaluated bilaterally, whereas 11 were evaluated unilaterally.

Background: Oral contraceptives, which may lead to thrombotic events, are widely used drugs by women in reproductive age, some of whom might need emergent or elective microsurgical intervention. This study was planned to investigate the effects of combined oral contraceptives (COC) on arterial anastomosis patency in female rat model.

Methods: A third generation COC (ethinyl estradiol and desogestrel) was used in this study.

Orbital hydatid cyst is a rare form of hydatidosis, comprising less than 1% of all hydatid cysts reported. The first choice of treatment for orbital hydatid cyst is surgery. Preoperative diagnosis is important, so as to avoid rupture of the cyst and prevent the spread of the parasitic disease.

The use of dynamic magnetic resonance imaging (MRI) of the breast as a complementary problem-solving tool was explored in a heterogeneous population sample. A total of 3,076 patients that underwent breast MRI examination between January 2008 and June 2012 in our center were screened retrospectively. Of these, 868 met the following inclusion criteria and were considered eligible for the study: available data on clinical signs, symptoms and on the results of mammography and ultrasound examinations in medical records; at least 1 year of follow-up; and documented pathology findings.

We report a 58-year-old male patient presenting with a 1-year history of presternal swelling and pain. Plain radiography revealed increased soft tissue density anterior to the body of the sternum, which showed cortical sclerosis. Computed tomography (CT) demonstrated ring-enhancing hypodense soft tissue masses surrounding the sternum, whose anterior and posterior cortices were markedly thickened.
