How Dr. Scott Diagnoses This Condition?
Dr. Scott uses a step-by-step approach:
Medical History and Physical Exam
He reviews your symptoms such as abdominal pain, bloating, weight loss, or changes in bowel habits, along with previous surgeries, medication use, and any known digestive or systemic conditions.
Laboratory Tests
Depending on CT findings, he may order blood tests including a complete blood count (CBC), liver and pancreatic enzymes, kidney function tests, and inflammatory markers (CRP/ESR) to support the diagnosis.
Review of CT Images
Dr. Scott carefully examines your contrast-enhanced CT scan to assess abnormalities such as bowel wall thickening, lymphadenopathy, ascites, fluid collections, strictures, or suspicious masses.
He compares current imaging with prior studies to determine progression, stability, or resolution of findings.
Endoscopic Assessment
When CT reveals concerning findings, Dr. Scott may recommend upper endoscopy or colonoscopy to directly examine the GI mucosa, obtain biopsies, or investigate sources of bleeding or obstruction.
Advanced Testing (if needed)
For deeper or unclear lesions, he may utilize endoscopic ultrasound (EUS), MRI enterography, or capsule endoscopy to evaluate the pancreas, small intestine, or submucosal masses. Biopsies may be taken for histological confirmation.
