Hyperintensiva lesioner huvud

Brain lesions are areas of brain tissue that show damage from injury or disease. The most common way to detect brain lesions is with diagnostic imaging scans. Depending on the cause, some types of brain lesions will heal on their own or are treatable.

However, some brain lesions are permanent or happen for reasons that can’t be treated or cured. To determine the malignancy rate for MRI-guided breast biopsies performed for T2 hyperintense breast lesions and to assess additional clinical and MRI characteristics that can predict benign and malignant outcomes. A retrospective chart review of consecutive MRI-guided breast biopsies performed in two tertiary hospitals was conducted over two years.

Biopsies performed for T2 hyperintense lesions were selected, and further lesion imaging characteristics and patient risk factors were collected. Univariate and multivariate modeling regression were used to determine additional imaging and patient factors associated with malignant outcomes for biopsies of T2 hyperintense lesions. Two biopsy-proven benign lesions were excluded as the patient was lost on follow-up. Our study observed a high malignancy rate, challenging the assumption that T2 hyperintensity can be considered a benign imaging characteristic for otherwise suspicious MRI-detected lesions.

Decision-making regarding tissue sampling should be made based on a thorough evaluation of more reliable additional demographic and imaging factors, including patient age and lesion size. Increasing patient age and increasing target lesion size are important predictors of a malignant breast biopsy for T2 hyperintense lesions. Lesion T2 intensity should be assessed for every target; however, additional imaging and clinical features should be used to guide decision-making regarding the need for tissue sampling.

Atrophie blanche The lesion signal intensity on T1 weighted images is usually compared to the adjacent skeletal muscle or intervertebral disc 1 and lesions with a higher signal intensity are referred to as high T1 bone lesions or T1 hyperintense bone lesions also take into consideration that some lesions might display a T1 signal much higher than skeletal muscle.
