Study Notes
Scenario
- 60-year-old smoker with chronic cough and chest pain
- Chest X-ray shows suspicious mass
- CT scan reveals 3 cm nodule in right upper lobe
- Irregular borders suggest malignancy
- Biopsy confirms non-small cell lung carcinoma (NSCLC)
Identify Pathology
- NSCLC accounts for 85% of lung cancers
- Often associated with smoking
- Irregular borders and upper lobe location on CT scan suggest malignancy
Why CT Scan is Best Modality
- High-resolution cross-sectional images for detailed visualization of lung nodules
- 3D imaging for assessing nodule size, shape, and location
- More sensitive than X-ray in detecting small lesions, important for early diagnosis
- IV contrast helps differentiate benign from malignant lesions
Patient History & Symptoms
- 60 years old with smoking history: Increased risk of lung cancer
- Chronic cough and chest pain: Common symptoms related to tumor growth and impact on nearby structures
- Suspicious chest X-ray findings: Requires further investigation (CT scan)
How to Perform the CT Scan
- Preparation: Explain procedure to patient, ensure understanding of IV contrast need. Inquire about allergies and renal function if contrast used.
- Positioning: Patient positioned supine, arms elevated above head to prevent artifacts
- Acquisition Parameters: Thin-slice protocol (e.g., 1-2 mm) for higher spatial resolution. Non-contrast and contrast-enhanced scans if indicated.
Post-Processing
- Multiplanar reconstruction (MPR) for better nodule evaluation in various planes
Analyze CT Scan (Image)**
- Nodule characteristics: 3 cm, irregular borders, suggestive of malignancy
- Location: Right upper lobe is a common primary lung cancer site
- Size: T1 tumor in TNM staging (needs further evaluation)
Confirm Diagnosis
- Biopsy confirmation required for final NSCLC diagnosis
- Histopathological examination provides type (e.g., adenocarcinoma, squamous cell carcinoma) and cellular characteristics
Discuss How Images are Stored & Accessed using PACS
- Images stored in Picture Archiving and Communication System (PACS)
- Digital storage, access by multiple users simultaneously
- Tools for image manipulation and sharing
Role of RIS in Scheduling & Managing CT Procedures
- Scheduling: Radiology Information System (RIS) manages appointments, patient preparation, and resources.
- Workflow Management: Tracks procedures, from order to image interpretation.
- Communication: Links with PACS, ensuring correct image labeling and organization
Discuss How the Patient's EHR Integrates Imaging Results into the HIS
- Integration of imaging results (from RIS and PACS) into the Hospital Information System (HIS)
- Comprehensive record with history, lab results, and imaging findings
- Access to imaging by authorized healthcare providers for better decisions and follow-up
