Breast Digital Infrared Analysis (DIRA) , a forgotten and set aside procedure.

Visita: termografiamamaria.blogspot.com (Version en Español)

Breast DIRA (previously named Thermography) already proved in the past that it´s use as an screening procedure had low specificity and high sensitive values for it to be recommended as an standard care Breast diagnosis tool .
Yet , until recently (last 5 years) active research mainly by Surgical Oncologists or Breast Surgeons have published interesting results.( Cornell NY , Addenbrooke Cambridge , Ville Marie Montreal , Taiwan and Mexico CEPREC)
FDA previous published criteria were prohibiting DIRA as well as the A.C. of Radiologists ( as an initial SCREENING TOOL)

Yet it has been cleared by the FDA approval as an adjunctive screening tool for breast cancer .( under 510 k) .

DIRA´s meaning is not an ANATOMIC or ARCHITECTURAL procedure ,it is a METABOLIC or PHYSIOLOGIC ONE so at first it ´s current recommendation should be only as a COMPLEMENTARY STUDY.

As such DIRA could help in specific scenarios, BIRADS 0,3,4 and give potential useful additional data in BIRADS5. EVEN BEFORE BIOPSY
Could aid mammogram in young,dense and breast prosthesis patients, and should be evaluated in other clinical scenarios as a Neoadyuvant Monitoring tool.
Finally as an early detecion procedure specifically in underdeveloped countries , could Triage in search of aggresive forms of the disease(T1,G2_G3). And aid Physical Exam of the Breast .

Availability , prompt attention and Specialized Diagnostic Aid.

Hi , with regret the following Surgical Oncology Scenario is quite common : 

Female on her early 50´s no previous history for breast cancer in her family , no other risk factors. 

  1. Palpable lesion on the left breast : NON CONCLUSIVE post OPEN biopsy pathological diagnosis and persistance of the original tumor near to the scar and undeterminate axillary lymph nodes
  2. Refered after a 2nd  NEGATIVE trucut biopsy to SURGICAL complete removal.

Started seeking for medical attention 13 , yes 13 Months previously with the following standard images:

(Remember please , unfortunately availability of excellent breast cancer diagnosis is far from ideal in the vast majority of  countries , in mine (Mexico)  it is estimated that after radiological suspicion for open population detection  , women start treament at least 9 months later.................some thing to think about and work for i believe  ) :(

Here they are:


 Dense Breast Tissue ++++
 Some Microcalcifications are seen Upper and 
 Outer Quadrant on the RIGHT side (remember palpable nodule on the LEFT) 
 Close up and amplification view: 




 Complementary Ultrasound IMage of the Left Lesion :
(remember after Biopsy) 



Morphology and Dimensions defined , anatomical concepts EASILY understood for the common health provider.....



I hope you agree with me as an Oncologist , enough suspicion is observed in order to recommend an open Biopsy of the LEFT nodule and in my opinion a radiologicaly guided on the RIGHT.

NOPE that did not happened , she was only sent for HER clinically evident left lesion.

So here I am with my Infrared Detector and stablishing or Aiding my Second Oncological Opinion :

Digital Infrared Analysis as a Complementary procedure in my patient:

 Basal Anterior View , infrared radiation is more obvious ont the left side , Mammary folds Irregularities , Left Axillary Predominance and an Isolated Thermal Summit coincidental with the Left PALPABLE lesion. 

But on the Right Side in the UPPER OUTER QUADRANT there is a Single Hyperthermia , that clinically is coincidental with the microcalcifications found on the Xray but not classified as SUSPICIOUS ( in the radiologist point of view) 



Physiologic series after cold challenge the same Hyperthermia is demostrated again.

Comment : Palpable Lesions are easy to biopsya ,and indications for them to be Biopsied are clear.

Infrared can Help :

"IDENTIFY SUBCLINICAL PALPABLE LESIONS"

In expert Hands (Oncologists Mainly) as a second look or opinion procedure is SAFE and can HELP Radiologists defined more clearly what they "consider" normal or abnormal.

Patient is on her way for BILATERAL BIOPSY ..results to be announced in the following weeks.

Keep posted and " open your minds for  a better future." EMC

Have a great weekend.
