RAD110 Chapter 3
| Question | Answer |
|---|---|
| Three chambers of thoracic cavity | pericardial, left + right pleural cavities |
| mediastinum | separates pleural cavities and contains all thoracic structures except lungs and pleurae |
| The diaphragm seperates... | the thoracic cavity from the abdominal cavity |
| respiratory system | consists of pharynx, trachea, bronchi, two lungs |
| trachea | fibrous, muscular tube with 16-20 C-shaped cartilaginous rings |
| carina | hook-like process that bifurcates the trachea |
| each primary bronchus... | enters corresponding lung (ex: right primary bronchus, left primary bronchus) |
| anatomy of bronchi | right primary bronchus is shorter, wider, and more vertical than left, make it easier for foreign bodies to enter the right |
| alveoli | alveolar ducts end in alveolar sacs, oxygen and carbon dioxide exchanged by diffusion in alveoli |
| anatomy of lungs | superior portion - apex inferior portion - base, rests obliquely on diaphragm sides - costrophrenic angles medial border - hilum |
| Which lung is shorter and broader, and why? Which has more lobes? | Right lung due to presence of liver, right has 3 lobes, left has two |
| lung movement during respiration | inferiorly during inspiration superiorly during expiration |
| inner and outer layers lungs | inner - visceral pleura outer - parietal pleura |
| pharynx | serves as a passage for air and food |
| neck | has thyroid, parathyroid, larger of submandibular glands |
| larynx | - located below root of tongue - suspended from the hyoid bone at level of the superior margin of the fourth cervical vertebra to it's junction with the trachea at the level of inferior margin of the sixth cervical verterbra |
| larynx is guarded by... | the epiglottis, which serves as a trap to prevent leakage into the larynx between acts of swallowing |
| AP soft tissue neck | - Radiation field size 12" lengthwise and 1" beyond skin line - patient upright or supine - central ray perpendicular through MSP at level of laryngeal prominence - exposure is made during slow inspiration to make sure trachea is filled with air |
| Lateral soft tissue neck | |
| In PA oblique chest such as RAO or LAO, is the side of interest closer to, or further from, the IR? (Hint: "A" is away) | further from IR |
| In AP oblique chest such as LPO or RPO, is the side of interest closer to, or further from, the IR? | closer to IR |
| What positions are used for a PA oblique chest? | RAO, LAO - follow the second letter |
| What positions are used for an AP oblique chest? | RPO, LAO, follow the second letter |
| How do you name projections? | The side the beam enters is the first letter |
| AP Chest | - supine or seated upright in wheelchair/stretcher, - used when patient can't stand |
| Describe lung and pleurae projections for AP or PA | - right or left lateral decubitis - to demonstrate fluid, patient should lie on affected side - to demonstrate air, patient should lie on unaffected side - patient needs to be in position for five minutes for buildup |
| Describe lung and pleurae projections for lateral | - Ventral (use prone position) or dorsal (use supine position) decubitis - patient needs to be in position for 5 minutes to allow fluid to settle or air to rise |
| AP/PA lateral decubitis | elevate body 2-3 inches |
| lateral ventral or dorsal positions | prone or supine, top of IR at level of thyroid cartilage |
