Longport Announces: Results of Burn Study • Initiation of Osteoporosis Study • Scanner Sale Update • Appointment of New Director

SWARTHMORE, Pennsylvania - September 24, 2001 - Longport, Inc. (OTC:LPTI) is pleased to announce the following:

St. Agnes Burn Center Study
According to Dr. John Millili, the director of St. Agnes Burn Center, the preliminary results of an ongoing study indicates that the Longport High Resolution Ultrasound Scanner provided a breakthrough in burn depth determination".

There have been many attempts to come up with a tool to accurately measure the depth of second-degree burns. This measurement is critical in determining whether to treat the burn surgically or conservatively. The St. Agnes study utilized Longports scanner to analyze 102 images. The results indicate that the scanner could easily and quickly allow for the differentiation between deep dermal injury and superficial dermal injury. Dr. Millili stated, Regardless of observer experience in burn evaluation, obliteration of the dermal/fat interface and widening of the dermal acoustic shadow provides reliable markers of deep thermal injury." Deep dermal injuries are best treated with immediate excision and grafting, where superficial injuries are best treated conservatively. These results should allow for better clinical results, less patient suffering and more economical treatments.

The results of this study will be presented at the 24th Annual Mid-Atlantic Burn Conference in November.

Initiation of Osteoporosis Study
A new study utilizing the Longport Digital Scanner is underway to demonstrate the correlation between skin thickness and osteoporosis. This study is designed to confirm the results of preliminary studies that indicated that the scanner has the potential to be useful in this endeavor. Professor I. Fogelman, who is one of the worlds authorities in osteoporosis research, will be involved in studies looking at a significant number of osteoporosis patients at Guys and St. Thomas Hospitals, London, UK. The studies will be comparing the results of the Longport scanner with the gold standard of osteoporosis identification, the DEXASCAN. The DEXASCAN utilizes x-ray radiation and is a more expensive exam.

Scanner Sale Update
The company has announced the sale of 2 scanners to a company involved in wound care in south Florida

About Longport, Inc.
Longport, Inc., is the developer of the Longport Digital Scanner (LDS), a high resolution, portable, digital ultrasound scanner that captures and reproduces images of soft tissue down to approximately 3 cm. The images are stored in a portable computer and can be e-mailed off-site for interpretation. The company has developed the LDS with multiple applications in mind, including wound management, identification of potential pressure ulcers, and detection of subtle changes in superficial tendons (i.e. Achilles, Extensor, and Flexor), ligaments (i.e. Ulnar Collateral), and soft tissue trauma.

The chief advantage to this process is that it will allow individual caregivers the opportunity to immediately assess and monitor patients with superficial soft tissue and muscle skeletal trauma, non-invasively.
