SCALES

  • 4 Review Spaces relating to 4 areas of major disease
    • Pleura – PTX and Effusions
    • Lungs – Pneumonia and Masses
    • Hila  – Masses and CHF
    • Heart – Megalies and Failure
First Scale – Pleural Run

 

PANORAMA WALK FOR PLEURAL ASSESSMENT
Ashley Davidoff MD

Pattern – start at the white lines  to the right and left of the thoracic vertebra running along the diaphragms into the pleural recesses, up the lateral walls to the apices

2nd Scale – Lung Loops
LUNG LOOPS – UPPER MID AND LOWER
Ashley Davidoff MD
  • Pattern –
      • Come down the trachea and and
      • loop the upper lung fields, then the
      • mid lung fields, and finally the
      • lower lung fields
      • looking for
        • symmetry,
        • masses,
        • infiltrates,
        • interstitial changes
3rd Scale – Skiing on the Moguls
SKI TRIP DOWN THE MOGULS OF THE HEART
A methodical approach to evaluation of the cardiac silhouette is likened to skiing down a mogul laden ski slope and then taking a trip on the ski lift back to the top of the mountain. The ski slope starts at the left subclavian artery (light brown)
, followed by the mogul of the aortic knob (bright green) at the bottom of which is the A-P window (white) only to be presented with a second mogul of the main pulmonary artery(yellow), and then the bay of the left atrial appendage (pink)and finally free at last of moguls and an exciting and accelerating ski down the LV (red)
We then have to take a walk back to the ski lift. At the junction of the LV (red) and the RV (blue) , if we take a right ward look up the mountain we can spot the LAD on top of the interventricular septum.
The walk along the border of the RV is terminated at the junction of the RV (dark blue) and the right atrium (light blue). At this point we wait in line to get on to the ski lift. We ride up the right hand border of the right atrium (light blue) a little rough bump over the ascending aorta )maroon) and then straight to the top along the SVC (pink).
Ashley Davidoff MD
  • Pattern of the Ski Run –
  • Start at the left apex at the left subclavian artery,
  • jump the aortic mogul and
  • land in the AP window, and then
  • jump the PA mogul,
  • land in the LA appendiceal  bay, and then
  • ski all the way down the LV.
  • Walk back to the ski lift via the inferior border of the RV and then the RA.
  • At the bottom of the RA get on to the ski lift as the IVC enters the RA
  • and then take the lift up the mountain via the RA ,
  • portion of the ascending aorta and the
  • the SVC

4th  Scale – Hilar Hoops

PRESSURE PUZZLES
Down the airways for the carinal angle
Upper vs Lower Vessels
Artery vs Bronchus
Middle – Hilar Size and Shape
Lower – Descending Bronchovascular Bundle and specifically RPA yellow arrow
Ashley Davidoff MD
  • Pattern of the Hilar Hoops –
      • Trip down the trachea – Specifically to look at the carinal angle
      • Upper hoop specifically to look at pa- bronchus ratio
      • Middle Hoop – Specifically to look at hilar size and shape
      • Lower Hoop – Specifically to look for redistribution and clarity of RPA
