Opinion on use of additional safeguards such as an intervention checklist, while divided, suggested that a modified checklist is called for in complex procedures involving recall of patient at a different date, multiple radiologists involved and therapeutic procedures under vacuum guidance.
The initial launch using rockets upset the gyroscopes, and radio guidance was unreliable because vacuum tubes suffered under high acceleration.Radar mapping was attempted on Matador, but suffered from the limitations of 1950s computers.
This vacuum in guidance also has an impact on access to generic versions of LAMB produced and marketed in other countries.
"If there is a vacuum in the guidance from Baghdad or from Washington, Petraeus will study the situation and take action," said Gordon Rudd, the historian for the Office of Reconstruction and Humanitarian Assistance, the civilian authority in Iraq before Mr. Bremer's appointment.
One patient with indeterminate calcifications underwent biopsy with stereotactic guidance and an 11-gauge, vacuum-assisted device.
Guidance is given concerning filling techniques (gravity or vacuum fill), the formation process, charging techniques, and formation algorithms.
Vacuum-assisted biopsy devices under ultrasound guidance have been used as an alternative to conventional ultrasound CNB.
As there is no article in the Treaties of the EC that provides guidance for the transfer of these competencies, there is a significant legal vacuum on issues of mixed competencies in the European Union (EU).
Although models can provide guidance in the face of limited evidence, they cannot overcome the evidence vacuum which characterises several important real-world aspects of screening.
In addition to needle localization, core biopsy and vacuum-assisted core biopsies are currently being performed under magnetic resonance guidance at centers around the world.
The first vacuum-assisted core biopsy (VACB) apparatus in the UK was installed for clinical use with stereotactic guidance at King's College Hospital in 1998.
