Keterangan
Pencitraan perawatan kritis menggunakan teknik canggih seperti pemindaian CT, sinar-X, dan ultrasonografi untuk memberikan informasi diagnostik yang akurat. Pencitraan langsung membantu dalam evaluasi cepat kondisi kritis, memandu intervensi tepat waktu untuk hasil pasien yang lebih baik. Pencitraan serial membantu melacak perkembangan atau kemunduran penyakit kritis, membantu dalam penyesuaian pengobatan yang dinamis. Pencitraan perawatan kritis menawarkan cara non-invasif untuk memvisualisasikan organ dalam, pembuluh darah, dan kelainan secara real-time. Pencitraan berfungsi sebagai panduan untuk prosedur invasif, memastikan keakuratan dan meminimalkan risiko selama intervensi kritis. Dalam perawatan kritis, pencitraan sangat penting untuk menilai kondisi neurologis, termasuk cedera otak traumatis atau stroke. Pencitraan perawatan kritis membantu memetakan struktur vaskular, mengidentifikasi gumpalan, aneurisma, atau kelainan lain yang memengaruhi aliran darah. Integrasi berbagai modalitas pencitraan meningkatkan pemahaman menyeluruh tentang kondisi kritis yang kompleks. Kemajuan seperti pencitraan di samping tempat tidur memungkinkan pemantauan berkelanjutan, memfasilitasi penyesuaian waktu nyata dalam manajemen perawatan kritis.
Ringkasan
- In the ICU, X-rays, especially of the chest, are frequently performed. Understanding the specifics of ICU radiology is vital, differentiating it from standard ambulatory radiology, particularly due to the common use of the AP view which can distort the heart appearance. Analyzing mounting devices, lines, and potential complications related to these devices is essential, alongside recognizing prevalent ICU disorders.
- When evaluating X-rays, elements like bone and soft tissue shadows, air, densities, and exposures should be considered. AP views are common in the ICU due to patient positioning, but they should not be used to comment on heart size. Lateral views are less common but can be helpful for identifying lung lobes. Exposure, rotation, and patient centralization are critical factors influencing interpretation.
- Device placement is a key element to consider. Endotracheal tubes, chest tubes, NG tubes, central venous catheters, pacemakers, IABP balloons, and ECMO cannulas are common, and their correct positioning must be verified. Incorrect positioning can lead to complications like lung collapse or recirculation in ECMO.
- Differentiating between common lung pathologies requires understanding that air appears black and fluid or infection appears white on X-rays. Conditions like pneumothorax, effusions, consolidation, collapse, fibrosis, masses, and pulmonary edema have distinct radiographic characteristics. Ultrasound is often more sensitive for detecting smaller effusions.
- CT scans provide more detailed anatomical information compared to X-rays. CT head scans have brain and soft tissue windows for detecting blood, fractures, and other abnormalities. CT angiography can visualize cerebral arteries, helping to diagnose strokes. Ischemic strokes appear dark, while hemorrhagic strokes appear white on CT scans.
- CT chest scans utilize soft tissue and lung windows to evaluate the parenchyma and mediastinum. Contrast CT pulmonary angiography is useful for detecting pulmonary emboli. Conditions like consolidation, pneumonia, pulmonary edema, and cavitation can be visualized on CT chest.
- CT abdomen scans can reveal abnormalities like pancreatitis, liver abscesses, and toxic megacolon. Pancreatitis is characterized by an enlarged pancreas, obscured pancreatic shadows, and surrounding fluid. Liver abscesses appear as fluid-filled cavities with defined walls.
