Breast MRI-the Importance of Type II and III Dynamic Curves Evaluation and Framing in BI-RADS 4C and 5 Score.

BACKGROUND: Breast Magnetic Resonance Imaging (MRI) offers the highest sensitivity in detecting breast cancer among existing clinical and imaging techniques, making it a crucial component of breast imaging protocols. This study aims to investigate MRI importance in correlation with previous imaging discordant procedures performed as echography and/or mammography to evaluate characteristics and framing in high-risk BI-RADS 4C or 5 categories based on morphological features and kinetic curves of masses found in the breasts of patients from our database. METHODS: A retrospective study with related statistical analysis was performed on a group of 33 cases, selected from a total of 488 patients who underwent breast MRI examinations at SPAD Imaging International S.R.L. Craiova, between 01.01.2021 and 31.12.2023, aged between 33 and 75 years. In all patients, MRI images parameters were analysed. RESULTS: In 33 patients, 23 had a single lesion and 10 had multiple lesions, 9 of them in the ipsilateral breast and, as a particularity, one of them, located in the contralateral breast. In 21 of the total patients with multiple or single lesions they had type III curves, which were classified in the BI-RADS 5 category, considering both criteria-morphology and type of curve, where the other previous techniques had not mentioned an increased risk, hence revealing that the situation in a percentage of 63.63 in the case of MRI investigation proved to be clearly superior. CONCLUSION: Combining both kinetic and morphologic criteria can enhance the diagnostic accuracy of MRI in breast lesion evaluation.

Imaging Aspects of Enchondromas in Pediatric Patients.

Enchondromas are benign tumors located primarily in long bones, some of which can be accidentally discovered during imaging exams conducted for other pathologies. These benign cartilaginous tumors are hard to differentiate from low grade chondrosarcomas, which require periodic follow ups. The purpose of this study was to identify the incidence of enchondromas in pediatric patients, to determine medical imaging criteria (Computed Tomography-CT and Magnetic Resonance Imaging-MRI) in order to differentiate enchondromas from other atypical cartilaginous tumors, and to identify a potential correlation between imaging aspects and clinical signs. The aim of this study was to review imaging findings of enchondromas in children.

Diagnosis and evolution of the benign tumor osteochondroma.

Osteochondroma represents a bone outgrowth covered by cartilaginous tissue and localized on the external surface of the bone. The incidence of osteochondroma is 20-35% of all pediatric benign tumors. Osteochondromas can be present in solitary or multiple forms and usually occur in the metaphysis of long bones in immature skeletons. The present study aimed to retrospectively determine the association between imaging diagnostic accuracy and histopathological examinations, which are the main methods of diagnosis for this type of tumor. A total of 66 patients presenting with radiological aspects of osteochondroma were initially selected; however, only the 56 patients who had a positive histopathological diagnosis of osteochondroma were eventually included in this study. Patient characteristics were taken into consideration and included age, sex, lesion localization, lesion imaging semiotics and histopathological aspects. Osteochondromas are generally asymptomatic lesions that are often incidentally diagnosed after trauma, which makes it difficult to determine the exact incidence of this pathology.

Imaging of the Posttraumatic Knee in Pediatric Patients.

Owing to its continuous transformation, the musculoskeletal system of pediatric patients presents some unique features with respect to both anatomy and physiology. The lesional pattern of the knee in pediatric patients is both similar to and in many aspects different from the lesional pattern in adults with knee injuries. In the case of pediatric patients, meniscal, tendinous and ligamentous lesions occur most frequently as a consequence of traumatic episodes. The purpose of the present study is to emphasize the importance of MRI examinations in pediatric patients exhibiting symptoms of knee joint injury. The imaging assessment of the extent of the lesions, which can be either simple or complex alterations, can directly influence the clinical management of these cases by appreciating the growth potential of the specific segment of immature skeleton involved.
