Outline
Outline:

  • Introduction

  • Imaging modalities used to study the renal system

  • Anatomy and normal appearance of the renal system

  • Common pathological cases


Introduction
Introduction

  • What is the radiology?

    Radiology is a medical specialty that employs the use of imaging to both diagnose and treat disease visualized within the human body.

  • What is the renal system?


Outline1
Outline:

  • Introduction.

  • Imaging modalities used to study the renal system.

  • Anatomy and normal appearance of the renal system.

  • Common pathological cases.



Imaging modalities
Imaging modalities: image the renal system ?

  • Conventional X-Ray

  • IVU (intra-venous urogram) / X-Ray + Contrast

  • US

  • CT

  • MRI

  • Nuclear medicine


Imaging modalities1
Imaging modalities: image the renal system ?

  • Conventional X-Ray

  • IVU (intra-venous urogram) / X-Ray + Contrast

  • US

  • CT

  • MRI

  • Nuclear medicine

    ALL CAN BE USED


Conventional radiography x ray
Conventional Radiography (X-ray) image the renal system ?

  • +ve:

    • Cheap & widely available

    • Often used as first choice

  • -ve:

    • Radiation

    • Limited anatomy

  • Used for:

    • Evaluate abdomen pain

    • Some time good for diagnosing kidney stones


  • Radio lucent image the renal system ? black (air)

  • Radio opaque  white (bone/stone)


Radiograph x ray
Radiograph (X-ray) image the renal system ?

Where are the kidneys ??


Radiograph x ray1
Radiograph (X-ray) image the renal system ?

Where are the kidneys ??


IVU image the renal system ?

  • Same as X ray but with IV contrast


IVU image the renal system ?

  • +ve:

    • Cheap & available

  • -ve:

    • Radiation

    • Needs IV contrast (?reaction)

    • Old (replaced by CT & MRI)

  • Used for:

    • To diagnose kidney stones

    • To diagnose hydronephrosis


US image the renal system ?

  • Ultrasound.

  • Use high frequency sound wave.

  • Contrast between tissue is determined by sound reflection.


US image the renal system ?

  • + ve:

    • Available

    • No radiation

    • Good anatomy

  • - ve:

    • Operator dependent

  • Used for:

    • Good for kidney stones

    • Excellent for hydronephrosis

    • Excellent for focal lesion e.g. cysts, masses


  • Hyper-echoic image the renal system ? white

  • Hypo-echoic  grey

  • An-echoic black (fluid)


CT: image the renal system ?

  • + ve:

    • Relatively available (more then MRI)

    • Very good anatomy

  • - ve:

    • Radiation

    • Some times need IV contrast (? reaction)

  • Used for:

    • Excellent for kidney stones (the best)

    • Excellent for hydronephrosis & masses

    • Excellent for kidney trauma


  • Hyper-dense image the renal system ? white (stone/bone)

  • Hypo-dense grey to black (fat/fluid)


CT image the renal system ?


MRI image the renal system ?

  • + ve:

    • Excellent anatomy details

    • No radiation

  • - ve:

    • Expensive

    • Long scanning time (30 to 60 min)

    • Not used to diagnosed kidney stone

  • Used for:

    • Excellent for masses

    • Good for hydronephrosis



MRI image the renal system ?


MRI image the renal system ?


Nuclear medicine
Nuclear medicine image the renal system ?

  • + ve:

    • Excellent to assess function

  • - ve:

    • Radiation

    • Poor anatomy details

  • Used for:

    • Evaluated function

    • Evaluated obstruction


Nuclear medicine1
Nuclear medicine image the renal system ?

  • Image features:

  • Projectional image.

  • Image contrast by tissue uptake and metabolism.


NM image the renal system ?


Objectives
Objectives: image the renal system ?

  • Introduction.

  • Imaging modalities used to study the back.

  • Anatomy and normal appearance of the back.

  • Common pathological cases.
