Could a Menstrual Blood Test Diagnose Endometriosis Earlier?
Discover how a menstrual blood test may revolutionize endometriosis diagnosis. Learn about new research and its potential impact on early detection.
Explore how endometriosis is detected and distinguished: differential diagnosis, biomarkers, ultrasound, and MRI—what each test shows, when it’s used, and how results guide accurate, timely care.
Reliable evaluation of endometriosis depends on understanding what each diagnostic tool reveals about the pelvis. Expert Ultrasound and MRI are the most valuable imaging methods, each offering unique strengths. Ultrasound is excellent for identifying endometriomas and certain deep lesions, while MRI provides a comprehensive map of structures affected by disease and is especially useful for planning treatment, including Excision Surgery when that is indicated.
Imaging also plays a critical role when symptoms resemble overlapping conditions such as IBS / IBD or Interstitial Cystitis. Differentiating these possibilities helps target the right therapeutic approach and prevents delays in care.
Even with advanced technology, many lesions—especially superficial or microscopic ones—remain invisible. A normal scan does not rule out endometriosis, nor does an abnormal scan determine the full extent of disease. Understanding what imaging can and cannot show leads to better expectations and more informed decisions about next steps in treatment and symptom management.
No. Imaging can strongly suggest disease but cannot detect every lesion, especially superficial or microscopic ones.
They provide different types of information. Ultrasound is ideal for ovarian cysts and some deep lesions, while MRI maps the entire pelvis in greater detail.
Many forms of disease are too small or too subtle to appear on imaging, yet still cause significant pain.
Before planning treatment, when symptoms overlap with GI or bladder disorders, and when evaluating suspected deep infiltrating disease.
Imaging contributes valuable clues, but diagnosis relies on a combination of scan findings, exam results, and symptom patterns.
